Thanks to Goodwin’s careful selection of raw materials, SCP silicone rubber can offer the rubber yet give massively increased performances.

– Variety of choice from Soft to High Hardnesss
– Excellent Tear and Tensile Strength
–  SCP rubbers produce waxes with an extremely smooth high shine finish that won’t         stick to the mold. Smooth shiny waxes means faster cleaning and less polishing of finished castings.- Excellent Wax Surface Finish
– Excellent return to shape, or “memory”.
–  High thermal conductivity means that waxes cool more quickly, increasing the  number    of wax patterns that can be made per hour.
