Bio-Based Reinforcing Fillers for PVC Composites

At BioPowder.com, we have specialized in producing customized PVC fillers (filler for PVC) and natural additives for PVC compounds. PVC and other soft synthetic polymers increasingly are looked at through the lens of environmental considerations. While PVC is not known as the most ecological solution for flooring systems, hoses, closures and countless other items of daily use, there are eco-friendly alternatives. Our mission is to support R&D professionals and manufacturers in creating effective, lasting, healthy and sustainable solutions.

This is best done through PVC fillers (filler for PVC), where a natural solid fibre is incorporated in a PVC matrix. Our team has developed a PVC additive that is not only bio-based and biodegradable, but that comes with new performance benefits for PVC compounds of many types. Our PVC additive is derived from natural side streams and suitable for bio PVC, composite PVC and similar materials.

Bio-based PVC fillers (filler for PVC) and texturing solutions for PVC flooring systems and linoleum

We're proud of ourselves on supplying highly effective PVC fillers (filler for PVC) and texturing agents for a wide range of flooring systems. Any PVC-based formulation, e.g. bio PVC or composite PVC, can be mixed with BioPowder.com PVC fillers powders to achieve the following results:

  • Abrasion resistance: especially interesting for floorings that are created to bear high loads, i.e. for industrial premises, schools, sports facilities or outdoor areas.
  • Significant bio-based percentage: to improve recyclability, safety and to minimize the overall carbon footprint of traditionally synthetic floorings
  • Reinforcing properties: PVC is a soft material whose strength and stability are greatly enhanced when mixed with our eco-friendly PVC fillers (filler for PVC).
  • Texturing options: our wide range of granular PVC additives – reaching from fine powders up to coarse particles – facilitates the creation of any textured surface. Besides the aesthetical variety that can easily be achieved, our functional PVC fillers (filler for PVC) are excellent anti-slip particles to be integrated in surface coatings made from PVC compounds or bio PVC.

BioPowder.com PVC additives are made entirely from renewable, circular resources – especially upcycled olive pits. These lignocellulosic materials are equally suitable for bio-based linoleum floorings, such as liquid linoleum. Such formulations are mostly-oil based and applied by pouring onto a hard surface. Recent trends include PVC- and VOC-free formulae with no formaldehydes, no plasticizers and no heavy metals. The BioPowder.com team supports such initiatives by providing solid, plant-based PVC fillers (filler for PVC) that can help reduce the amount of required additives and accelerate curing.

Our team can support you during all phases of research and development up to product launch. Effective guide formulations can be provided just as ready-made bio-linoleum solutions: our naturazzO Resilient Flooring system is free of PVC, VOC, BisPhenol A and isocyanates and can be made in a variety of colors and textures. It is a natural formulation with a unique combination of bio-fillers – olive stone functional powder and fine recycled marble. Please contact us for further guidance and product specifications.

Bio-based PVC fillers (filler for PVC) for molded bio PVC and PVC composites

Hoses, PVC-rubber composites, tyre components…there is a wide range of objects made by molding PVC-based formulations. All of these can be made bio-based by adding a certain percentage of BioPowder.com natural PVC additives. 

Optimal dispersion and blending with PVC can be achieved when using a fine powder. Our product range Olea FP (Functional Powder) is made from natural olive stones and can be tailored to a variety of grain size ranges.

Traditionally, PVC composites were manufactured with mineral fillers such as calcium carbonate. Our powders were developed as sustainable alternatives that come with the following advantages:

  • Strength and stability: the high hardness and amorphous particle shape of BioPowder.com PVC fillers make them excellent reinforcing agents. They are versatile polymer additives that can enhance impact resistance and stability of diverse types of bio-based PVC.
  • Biodegradability: suitable for biodegradable applications such as packaging materials, films and foils; no premature degradation will occur when bonded firmly in PVC compounds. 
  • Light weight: BioPowder.com Olea FP only have a fraction of the density of mineral PVC fillers. This makes them ideal alternatives for lightweight components designed for automotive, aviation, shipbuilding and other high-tech applications.

Treated variants of Olea FP for PVC compounds and bio PVC

Our powder and granular additives can be supplied in a natural form (i.e. 100% olive stone-based) or treated in the following ways:

  • Colored: for appealing color effects in surface coatings or design objects
  • Dehydrated: for easy extrusion or compounding without moisture exhaust
  • Hydrophobic: for versatile use in impermeable and/or water-repellent compounds

BioPowder.com powdery fillers can be custom-made in small and large batches. We ship worldwide and offer assistance throughout all phases of R&D.

Frequently Asked Questions (FAQ): Filler for PVC and PVC Compounds

1. What are PVC compounds and bio PVC?

Basically any material in which PVC is combined or filled with another material. The word "composite" is used for a material made up of two or more components. In material science, it generally describes a binder and a filler. When it comes to PVC compounds, the base material or binder is often virgin or recycled PVC while the filler is a powdery mineral or - as promoted in recent times - a plant-based or biodegradable filler for PVC. PVC compounds are often developed with the goal of enhancing the mechanical properties and of minimizing the use of PVC, which is a potentially harmful chemical substance.

2. Why are additives used in PVC?

For many reasons and in most cases to change and enhance the technical properties. PVC compounds are very diverse, and so are fillers for PVC. In high-load applications such as PVC coatings, a filler for PVC is mostly incorporated into the matrix to increase hardness and abrasion resistance. In other occasions, softeners are used to make the PVC more elastic and flexible. In bio PVC, a bio-content as high as possible is the goal, and hence plant-based (reinforcing) additives are chosen.

3. What additives make PVC flexible?

To make PVC a flexible plastic, the commonly used chemicals are plasticizers. They are generally synthetic and fall in the categories of benzoates, phtalates or adipates. In bio based PVC, research has demonstrated the effectiveness of plant-based plasticizers such as castor oil derivatives as plasticizers.

4. Which regulatory framework governs BioPowder.com PVC fillers?

Our renewable powder ranges is derived exclusively from natural resources, i.e. by-products of the olive and fruit processing industry. Hence, any BioPowder.com filler for PVC qualifies as an agricultural raw material and is exempt from chemicals-related regulations, such as Regulation (EC) 1907/2006 (REACH).

5. Can any PVC filler materials be used in composite PVC?

As a general rule, a fine powder filler for PVC is the best choice. The smaller the particle diameter, the better the PVC fillers can be dispersed in the PVC matrix. Good dispersion helps reduce brittleness in the PVC compound and create an even surface. In combination with plasticizers as mentioned in question 3, flexible composite PVC can be produced, e.g. for soft materials used in hoses or pipes. 

6. How fine can you make your PVC fillers?

We are aware of the need for very fine powders as additives used in PVC. Therefore, our powder range goes below 50, 25 and in some instances also 10 microns. Thanks to our state-of-the-art manufacturing techniques, our PVC additive solutions can be produced in bespoke micron ranges. In cases where surface texturing is desired, e.g. in PVC floorings, our offer also includes coarser particles to create visual or haptic effects (such as anti-slip surfaces).  

7. Which raw materials do you uses for your PVC fillers

Only circular, renewable by-products from the fruit and olive processing industry. All our raw materials contribute to waste reduction and our bio based PVC additive manufacturing ticks all the boxes in terms of sustainability. We keep the resource use (land, water, electricity) down to a minimum, source locally and use environmentally friendly transport solutions for delivery. The carbon footprint of our PVC fillers is therefore considerably better than for the conventional synthetic powders. Nearly any filler PVC might require can be sourced from non-chemical, natural resources. Our mission is to support you in choosing the best PVC filler materials.

8. Which quantities of PVC additives do you supply?

We are an industrial manufacturer and cater to a B2B audience. Therefore, our minimum order quantity is 25 kg. We supply both small and large batches, as well as samples for laboratory testing. Any BioPowder.com filler for PVC can be produced all year round and shipped to nearly any destination worldwide. Our long-standing experience and logistics network allows us to guarantee stable supplies of our PVC fillers and tailored solutions for a variety of requirements.
