Polyester Mat
GENERAL INFORMATION
Polyester mat is a nonwoven material, manufactured with high grade virgin PET chips or polyester staple fiber. Polyester mat has excellent tensile & tearing strength, extensibility & thermal stability, as well as low shrinkage performance. After saturation with bitumen, the roofing membrane finished product is extremely elastic and has high resistance to aging & corrosion.
Based on raw material & production process difference, we have mainly two types of polyester mat: Long Fiber Polyester Mat (Virgin PET Chips as raw material, produced with spunbond technology, needle punched for mechanical integrity and chemically bonded to increase stiffness) and Staple Fiber Polyester Mat (Polyester Staple Fiber as raw material, produced with dry laid technology, needle punched for mechanical integrity and chemically bonded to increase stiffness).
APPLICATION
Polyester mat is an idea carrier material for bituminous waterproofing membrane. The membrane produced with polyester mat is widely used in various types of construction waterproofing & corrosion resistance circumstances, such as roof, bridge, wall, tunnel, underground, water pool, basement, etc.
