SiSiB® PC5022 can be used as an intermediate for other functional organosilanes and silicone fluids.

In the rubber industry, the strength of polyurethane elastomer can be enhanced by inducing polarized chloropropyl group from this product. SiSiB® PC5022 is also applicable to synthesize vulcanized rubber with low penetrativity, low rolling resistance and high elasticity & elongation rate.

In the plastic industry, SiSiB® PC5022 can be used to restrain the penetrating out of PVC additive, keeping the plastic clean, can also be used as absorbent for polyurethane foam to improve its climate adaptability.
In the textile industry, fabric can be softened and more elasticized by an agent from SiSiB® PC5022.
