PVC Type 1 – Normal impact, excellent chemical and corrosion resistance, easy to fabricate, weld or machine
PVC Type 2 – High impact, excellent chemical and corrosion resistance, easy to fabricate, weld or machine
CPVC – High heat and corrosion resistant CPVC sheet. Excellent corrosion resistance at elevated temperatures.
Bonding PVC – Easily achieved by using Plexus® MA300, a fast-setting methacrylate adhesive, to create stronger bonds than the PVC itself.
Tech Tip – PVC also comes in fire safe materials specially formulated to exceed FM 4910 fire compliances in semiconductor and cleanroom applications.
