​​Chopped Strand Mat 450 GSM High Temperature Chemical-Resistant Hand Lay Up Vacuum Infusion Composite Mat​​

​​1. Product Overview & Features​​

​​Chopped Strand Mat 450 GSM​​ is a non-woven reinforcement material made from ​​E-glass fibers (50mm in length)​​ randomly distributed and bonded with powder/latex binders, offering a weight of 450g/m². Key advantages include:

​​High Mechanical Strength​​: Longitudinal and transverse tensile strength ≥70N/150mm, ideal for high-load applications (e.g., boat hulls, automotive parts).

​​Chemical Resistance​​: Withstands acids, alkalis, oils, and solvents, suitable for marine and industrial environments.

​​Easy Processing​​: Compatible with hand lay-up, filament winding, RTM, and vacuum infusion processes.

​​Lightweight Design​​: Low density and uniform structure reduce finished product weight.

​​Regulatory Compliance​​: Passes RoHS, REACH, and UL94 certifications, with no asbestos content.
