Description
Castaldo® SuperStretch™ offers fantastic tear strength that allows mold makers the ability to make standard two-part molds of designs that formerly required complicated multi-piece molds with difficult cores and inserts. Like all Castaldo silicone jewellery molding rubber compounds, SuperStretch™ is easy to pack, easy to cut and requires no silicone mold release sprays.
Waxes come out with a glossy high shine finish, meaning castings will require less finishing. Rubber shrinkage is very low at only 1.3%. SuperStretch™ is compatible with other Castaldo silicone rubber products so that it can be used alone or as an insert for special projects.
Sold in 5 lbs. box of strips that measures approximately 2-7/8" wide x 18" long. Vulcanizes at: 165° -176°C / 330°-350°F for 15 minutes per layer. Made in Thailand.
