Product Description
PMC™-780 WET
PMC™-780 is a premium performance urethane rubber that offers exceptional strength, durability and abrasion resistance. PMC™-780 DOES NOT CONTAIN MOCA – a known cancer causing agent and hazard. Mixed two parts A to one part B by weight or volume, PMC™-780 urethane pours easily and cures at room temperature with negligible shrinkage to a solid Shore 80A rubber.
Ecoflex™ 00-50
Ecoflex™ rubbers are platinum-catalyzed silicones that are versatile and easy to use. Ecoflex™ rubbers are mixed 1A:1B by weight or volume and cured at room temperature with negligible shrinkage. Low viscosity ensures easy mixing and de-airing, or you can choose to mix and dispense using our convenient dispensing cartridges. Cured rubber is very soft, very strong and very “stretchy”, stretching many times its original size without tearing and will rebound to its original form without distortion.
