WELLPREN®RESIN: IM SERIESimage.png
CPE is one of the most important impact modifiers for the universal plastics market. Compared with other impact modifiers like AIM (Acrylic Impact Modifier), MBS and ABS, CPE is more competitive in its comprehensive performances and price. Currently CPE is favored by more and more customers and it is expanding to bigger share of the impact modifier market.
Proper amount of WELLPREN®RESIN added into formulations of PVC, PE or PP plastic products will not only greatly enhance impact resistance but will largely improve low temperature performances, weatherability, welding strength and other performances. WELLPREN®RESIN is most suitable for substitution of Acrylic impact modifier (AIM) or blending with Acrylic impact modifier (AIM) with a certain percentage without adjusting the processing data and the formulation, resulting in an optimum performance /cost solution.
All in, WELLPREN®RESIN helps fabricators and compounders meet increasing critically performance requirements and cost control needs.

Application of WELLPREN®RESIN

1. Impact modifier for rigid and semi-flexible products

WELLPREN®RESIN improves greatly the impact resistance, low temperature performances, weatherability, and welding strength of the final products.


2. Application in Flame Retardant ABS

Addition of certain percentage of WELLPREN®RESIN into flame retardant ABS formulation will not only avoid using of big amount of inorganic flame retardants in the formulation, which causes physical performance lost, but will play positive role in enhancing the flame retardancy of the whole system and substantially improve the impact strength of the end product. (TV set; Computer etc.)


3. Application in soft products

As a good elastomer, WELLPREN®RESIN can be used directly for soft products. The soft products produced have superior weatherability and long service life.
