Description
QM 135 is a two-component, condensation-cure silicone elastomer designed for moldmaking applications requiring high tear strength and flexibility. The material cures at room temperature to form a durable rubber capable of reproducing intricate patterns and complex geometries.
With a 35 Shore A hardness and high elongation, QM 135 is well suited for molds that require flexibility during demolding while maintaining dimensional stability. It is commonly used for statues, furniture, architectural elements, and prototype molds.
