Polypropylene (PP) It is obtained by polymerising propylene in the presence of Ziegler-Natta catalyst. It is chemically inert and resistant to attack by corrosive reagent. WebX-Profile Oil-Resistant Buna-N O-Rings. Also known as Quattro Seals and X- rings, these X-profile O-rings have four points of contact for a better seal in dynamic applications than round-profile O- rings. They also require less compression to make a seal, so they offer a longer service life.
