HY-E628 Addition Curing Platinum Silicone Rubber 28 Shore A for Prototype and Resin Molds

Summary: HY-E628 is a 28 Shore A addition curing Platinum silicone rubber for prototype molds and resin crafts, with low shrinkage and good flow into fine detail.

Product Overview

HY-E628 sits in the middle of the hardness range. Prototype shops pick it when a mold has to survive repeated cycles but still flex enough to release a thin-walled or sharp-cornered part.

Technical Specifications

Model HY-E628, 28 Shore A, two parts A and B, mixing ratio 1:1 or 10:1, semi transparent, service temperature -60C to 200C.

Product Features

No by-products during cure, so shrinkage stays low and the mold keeps the master dimensions. High tear strength suits angular masters.

How to Use

Stir A and B separately, weigh and mix for two to three minutes, degas, pour in a thin ribbon from one corner, cure at room temperature or with heat, then demould.

Application Scenarios

Prototype and vacuum casting masters, resin craft molds, plaster parts and soap moulds.

Buyer Benefits

Stable hardness between batches keeps repeat orders predictable. Trial quantities start at 10kg.

Certifications and Compliance

ISO9001, RoHS, REACH, FDA, UL and CE.

Customization Options

Hardness, colour, mixing ratio and packaging are open to customization.

Production Process

Pre-production sampling, batch mixing and full inspection before shipment.

FAQ

MOQ is 10kg. Curing time depends on temperature and section thickness. Samples are available.
