SFEP is committed to providing a package of solutions for the Resin Industry:


The application of WACKER HDK® in resin

UPR industry: The UPR polar system can be adjusted to form by adding or eliminating phenyl ethylene. WACKER HDK® Fumed silica, working as rheology controller, can stably increase both the viscosity and the thixotropy.

The application of imported hollow bubbles in resin industry:


The surface of hollow bubble is very smooth and its particle is even. It hardly absorbs resin and the specific gravity is extremely light. So, the weight and the melting viscosity of the whole system decrease dramatically. It can easily fill into the thinnest part in the resin and decrease the contractibility of the products.  Being made into light products, the hollow bubble also has the good processing performance. It’s easy to cut, drill and nail. To different extent, it’s chemical stability, impact resistance, toughness, stiffness and flame retardant resistance are all increased.
