Zotek F 42 HT LS PVDF Foam First To Be Awarded FM Global 4910 Approval
Walton, KY - Zotefoams Inc., one of the world's leading manufacturer of cross-linked block foams, has announced that its ZOTEK F 42 HT LS PVDF foam line has been awarded FM Global 4910 clean-room materials flammability test approval. It is believed that ZOTEK F 42 HT LS is the first foam insulation to meet the standards of this rigorous test protocol.
ZOTEK F 42 HT LS is a high-temperature foam recommended for use in a variety of sealing and insulation applications in the semiconductor, pharmaceutical and chemical-processing industries where exceptionally low smoke release and flame propagation is required in the event of fire. It can be used over a wide temperature range (-48°C to 155°C), during which the material maintains its ductility and resilience. ZOTEK F 42 HT LS also exhibits exceptionally low out-gassing of volatile organic compounds (VOCs) under Semiconductor Standards for clean rooms. This purity is based on Zotefoams' manufacturing process that expands engineering resins, such as ultra-pure Kynar PVDF resins, into high-performance foams through the use of only inert nitrogen gas, heat and pressure. ZOTEK F line of foams also show excellent chemical and UV resistance, primarily due to the base properties of Kynar PVDF polymers that are used in harsh chemical environments, and UV-resistant coatings for external structures. ZOTEK F foams exhibit only slight reduction in mechanical properties and show color retention even after long exposure to UV light.
A successful application of ZOTEK F 42 HT LS in clean environments is T-Tubes, an advanced insulation system that has been specifically developed for operator protection on hot steam lines in the Biotech industry. The closed-cell nature of ZOTEK F 42 HT LS allows for cutting and installing in clean environments without particulating. Combined with the sealed surface of the thermally molded T-Tubes, ZOTEK F 42 HT LS provides moisture and mold-growth resistance, and removes the need for the cumbersome jacketing that is used in other pipe-insulation systems. The insulation system is easy to install with custom-molded fittings such as elbows, Ts and valve covers with an overlapping self-adherent tape.
