Because these sheets resist swelling when exposed to water, they’re often fabricated into containers and parts for laboratory equipment. Polypropylene has a hard, slippery surface that won’t bind or stick to cutting tools, plus it provides good electrical insulation.

You'll get one piece of each material listed, except the Multipurpose pack, where you'll get two pieces (one piece of nylon 6/6 and one piece of cast nylon).

These sheets meet FM 4910, UL 94 5VA, and UL 94 V-0 for flame retardance. Widely used in semiconductor applications, they have excellent electrical insulating properties. Polypropylene has a hard, slippery surface that won’t bind or stick to cutting tools.

In addition to meeting UL standards for flame retardance, this film is an excellent electrical insulator, so it’s widely used in semiconductor applications.

Package food, textiles, and other products in wet environments. This film won’t absorb or swell from water. This film keeps its shape at room temperature. When heated, it softens evenly and won’t warp, making it a good choice for heat sealing and applications that involve shaping with pressure and heat.
