Specifications

Ultra-High Molecular Weight Processing Aids
HR-530,  HR-90, HR-910 is a new ultra-high molecular weight acrylic processing aid for rigid PVC and high quality foam applications. Its gives the following performance: low torque, faster fusion, high melt strength and expansion.

Performance:
1)Its fast fusion performance make PVC melt better in low temperature, then change flow of PVC                             effectively. 
2)Enhance melt strength, elongation and thermal elasticity, makes surface of PVC product excellent.
