An improved formulation of a uv concentrate for outdoor slit-tape applications is said to allow processors to crank up line speeds without triggering the usual downstream problems due to water carry-over.
An improved formulation of a uv concentrate for outdoor slit-tape applications is said to allow processors to crank up line speeds without triggering the usual downstream problems due to water carry-over. Available from Techmer PM, Rancho Dominguez, Calif., Techsperse PM11525E63 is suitable for both HDPE and PP slit tapes in woven bags for fertilizers, as well as climbing ropes, tarpaulins, tents, outdoor carpet backing, and pipe wrap. “We have been able to reduce water carry-over to very low levels—without affecting uv protection, says v.p. of technology Abe Mor. Typical uv stabilizers tend to attract water in the film quenching bath, which can lead to downstream film breakage and line shutdowns.
