CHO-THERM - Comercial Grade Thermally Conductive Electrical Insulator Pads

larger image

CHO-THERM® Commercial Grade Thermal Insulator Pads are designed for use where solid thermal and electrical properties are required at an economical price. These products are offered as dry pads, or with an optional adhesive (PSA) layer for attachment. Materials with PSA are available die-cut on continuous rolls. Versions are offered with either polyimide or fiberglass reinforcement to protect pads against tear, cut-through and punctures.

Features/Benefits

Good thermal properties

Good to excellent dielectric strength

Excellent mechanical strength and puncture resistance

Available with and without acrylic PSA

UL recognized V-0 flammability rating

Meet RoHS specifications

Available on continuous rolls for easy peel and stick application
