Platinum-Cured Silicone Rubber
Platinum-cured (also known as addition-cure), room temperature-curing silicones that cure to flexible, high-strength rubbers. Platinum-cured silicone rubber is an excellent mold material, but select silicone products are also widely used as a casting medium in applications including medical modeling, special effects, and orthotics.
Tin-Cured Silicone Rubber
Tin-cured (also known as condensation cure), room-temperature curing silicones are most commonly used to make flexible molds. Molds made from these rubbers exhibit high tear strength, good release properties, and resistance to high temperatures.
Compared to platinum-cured silicone rubbers, tin-cured silicones show less sensitivity to cure inhibition.
Silicone Foam
Silicone Foam is a platinum-cured silicone foam with a 15 lb/ft³ density. It is often used in conjunction with gel silicone rubbers to create prosthetic appliances and props.
"Prior to our relationship with Weaver Materiel, we were purchasing riser sleeves direct from the OEM. As a stocking distributor, Weaver typically is able to deliver same or next day. OEM lead times averaged three to four weeks. With Weaver, I've been able to reduce my working inventory by about 40%."
