Fluoroelastomer processing aids can improve the melt processibility of polyolefins only by depositing on the internal dies surfaces. It has been shown previously that other additives in the compound can interfere with deposition on the die surface. This present work expands on this knowledge by examining the effectiveness of several commercial processing aids when paired with various antiblocking agents in a LLDPE resin run on a blown film line.

The results show that fluoroelastomer processing aids can perform efficiently in the presence of antiblocking agents if they contain an interfacial agent. The interactions from most antiblocks can be effectively overcome by the use of such technology, however antiblocks that incorporate synthetic silica can be very interactive and reduce the overall efficiency of the polymer process aids.
