Materials
Valley Rubber work with a very wide range of materials in both solid and cellular form. We are happy to carry material development should our standard materials be unsuitable to meet the criteria of a particular project.
We are very aware that careful selection of the elastomer is essential to ensure that all design criteria are met. When selecting the type of rubber to be used it is necessary to consider some or all of the following:
- Mechanical properties - hardness, tensile strength, compression set
- Electrical properties - resistivity, conductivity
- Thermal properties - service temperature
- Environmental properties - weathering and ozone resistance, radiation resistance
- Chemical properties - oil or acid resistance
- Costs - some rubbers are much more expensive than others, therefore decisions have to be made as to whether durability is more important than cost
- Process to be used - 1) thermoplastic rubbers moulded on convential plastic injection equipment for high volume jobs would be processed using fast cycles for lower cost and increased outputs. 2) Compression moulding for single cavity prototype tools or single cavity production tools
The following are just some of the thermoset rubber we can offer;
Natural rubber NR, Styrene Butadiene SBR, Ethylene propylene EPDM, Nitrile NBR, Hydrogenated Nitrile HNBR, Silicone VMQ, Neoprene CR, Polynorbornene PNR, Polyacrylate ACM. ANM, Polyurethanes AU EU, Fluoro Silicone FVMQ
We also offer thermoplastic rubber (TPE/TPR). This material covers a very wide range of polymer types and can offer the end user a cost effective alternative to conventional thermoset rubbers and polymers. This can also be coloured.
