Perme-Shield demonstrates exceptional barrier properties to highly permeable acids and significantly defends against gas permeation and chemical leaching through the tubing walls used in wet chemical processing.

Simple design, superior technology
Perme-Shield is dual-layer, high-purity, PFA coextruded tubing with an inner layer that meets SEMI F57 approval. The outer layer is a new patented PFA copolymer that serves as a protective barrier layer, resulting in a higher level of acid permeation resistance when compared to conventional high-purity PFA tubing.
 

	Developed specifically for semiconductor manufacturers
	Exceptional barrier properties
	Higher acid permeation resistance than PFA HP alone

Lower replacement costs - and less downtime
Perme-Shield extends the life of both the wet chemical processing tube and the surrounding compounds within the equipment to levels previously unseen in the semiconductor industry.

Proven industry-standard materials
While the Perme-Shield advantage is provided by the patented outer layer technology, the inner fluid contact surface is the proven high-purity PFA (Daikin 231 SH) that has become an industry standard.

Cost benefits
The cost benefits of Perme-Shield are astounding. Tests have shown that its resistance to permeation and leaching allows it to provide significantly longer service life, thereby greatly reducing maintenance and replacement costs.
