CHT manufacture RTV silicone moulding rubbers which have easy mix ratios, cure at room temperature and offer fine detailed reproduction.
RTV silicone rubbers use two different types of silicone chemistry to form an elastomer: condensation cure systems, which use a tin based catalyst, and addition cure systems, which use platinum based catalyst. Although the end products can be very similar they do have some key differences which should always be considered when making your product selection. Click on the orange header for more information.
The differences between the two systems should not be referred to in terms of positives and negatives but rather properties that will provide benefits for different applications.
Where the application demands good dimensional stability, e.g. precision moulding, prototyping, making masters or very large objects, then addition cure would be the preferred choice. However, the shrinkage levels for a good condensation cure are still very low at about 0.5%. The reproduction and release properties of both materials are excellent as is the transfer of very fine detail.
CHT have a wide range of moulding rubber products which can be used for a variety of applications including food grade products for use with chocolate, icing sugar and other confectionery and skin rubber for using to create prosthetics or for use in special effects for films & theatre. Both high and low tear products are available.CHT moulding rubbers are also ideal for creating tampo print pads for printing on ceramics, plastics and metals.
