Product Application
FINE CPE can not only greatly enhance the impact modification performance, In particular low-temperature performances, weather-ability for soft PVC product but also give a higher welding strength of the final products and promote the rapid plasticization of PVC.
The special molecular structure makes FINE CPE series can be used directly for soft PVC products as a elastomer and give the fine products a superior weather-ability and better service life.
With its excellent flame retardancy and fluidity, FINE CPE can replace some plasticizers as permanent plasticizers for some PVC products and will not get migrated and volatilized even at high processing or service temperature.
Addition of certain percentage of FINE CPE 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 also will play positive role in enhancing the flame retardancy of the whole system and substantially improve the impact strength of the end product by its High impact modification performance, high filling efficiency.

Frequently Asked Questions
CPE offers superior comprehensive performance and cost efficiency compared to AIM, MBS, and ABS. It delivers excellent weatherability, chemical resistance, high corner strength, and good low-temperature impact strength while maintaining strong compatibility and high filling capacity.
Yes, CPE can substitute or blend with Acrylic Impact Modifiers (AIM) in specified ratios without requiring adjustments to processing parameters or formulations, providing an optimized and cost-effective compounding solution.
CPE135A and CPE3135 are the premier choices for rigid PVC profiles, doors, windows, sidings, fences, and pipes due to their high molecular weight, rapid fusion, and superior mechanical performance. CPE645 is also highly effective for premium siding and pipe applications.
CPE2035 features low chlorine content, low molecular weight, and excellent thermo-stability. It acts as a permanent modifier that reduces the need for excessive inorganic flame retardants, thereby preserving physical properties and boosting overall impact toughness.
Yes, FINE provides direct equivalent grades for classic Dow Tyrin series products with matching physical and chemical properties. For specific cross-reference charts and technical data sheets, contact info@fine-additive.com.
