Minicel
Description
[Volek] A registered trademark for a cross-linked Polyethylene foam manufactured by Sekisui Voltek, LLC. Like polyethylene foams, cross-linked polyethylene foams are durable and chemically stable, but are typically finer celled. [1] Minicel is a closed cell foam. It is an extremely fine-celled bun foam that has a smooth, consistent surface. Minicel has a tough and firm, yet elastic feel. [2] Minicel has good thermal insulation, strength and shock absorption. It is impervious to mildew, mold, rot, and bacteria, as well as chemical resistance. Standard colors are natural-white and black. Minicel is very buoyant and is commonly used in water recreation devices such as kayaks. [3]
