Platsil HTS-25 is a high-performance, platinum-catalysed silicone rubber. With excellent tear strength, tensile strength and elongation properties, this silicone stands up to the rigours of repetitive demoulding and/or stretching. Common applications include concrete casting, medical modelling and prototyping.
Physical Properties
– Mix Ratio by Weight 1A:10B
– Shore Hardness A25
– Pour Time 70 minutes
– Demould Time 24 hours
– Cured Colour Milky White
– Mixed Viscosity (cP) 15,500
– Elongation (%) >2,000
– Tensile Strength (psi) >645
Other silicones in the HTS-Series include Platsil HTS-25 Fast (a faster-setting version of the HTS-25) and Platsil HTS-40 (Shore A40).
Additional Key Characteristics
– Good Chemical Resistance – a good moulding choice when planning to cast polyesters, polyurethanes, epoxies and more.
– Excellent Release Properties – making release agents unnecessary in many mouldmaking applications.
– Polytek Additives – vary the viscosity, reduce or speed up the cure and demould times, and alter the colour of the cured rubber.
