Coupling Agents

A coupling agent is an additive which improves the interfacial properties of mineral fillers/natural fibres and polymers. They react (bond) with the filler surface and entangle with the polymer matrix or are at least compatible with it.

Reliable bonding with Yparex coupling agents

The Yparex coupling agents of The Compound Company achieve reliable chemical bonding between reinforced fibres and different polymers. They boost impact strength across a range of fibres – including our EcoForte range of glass-fibre reinforced and natural-fibre reinforced compounds.

Typical applications for Yparex coupling agents are:

– glass fibre reinforced compounds
– natural fibre reinforced compounds
– carbon fibre reinforced compounds
– mixture of fibres in reinforced compounds

Adhesion promotor for glass fibre reinforced compounds

Dependable adhesion is critical in the compounding business. That is why our Yparex coupling agents are used by manufacturers worldwide to boost adhesion with glass fibre. Yparex PO 1020 is the best choice of coupling agents for PPGF (polypropylene glass fibre reinforced) compounds in automotive to realise top class material strength in combination with very good impact strength and excellent emission properties.

Coupling agents for composite tapes

Yparex coupling agents show great processability in thermoplastic tapes production. The mechanical properties of the tapes are the best in the market. Yparex offers a wide range of coupling agents for both PE and PP fibre reinforced tapes.

Coupling agents for wood plastic composites

Due to the excellent rheological properties of Yparex P0 1020, mixing with the other WPC-components in PP based wood plastic composites is perfect. Independent studies have demonstrated not only outstanding mechanical strength but also a 5% lower energy consumption versus the reference material. For PE based wood plastic composites Yparex PE 1040 is an equally perfect material. Yparex can be used in its granulate form, skipping the expensive powdering step.

Biobased coupling agents

As a coupling agent, Yparex is ideal for chemical bonding between fillers, reinforcements and polymers. It is also available as a biobased coupling agent to increase impact strength in a more sustainable way.
