Material Forms

Here at Martin’s Rubber, we supply a wide range of bespoke products available in various materials. From moulding compounds to rubber insertion sheets and extruded rubber products, we aim to provide the perfect solution for you no matter what shape, size, thickness or material.

Our extensive range of materials include:

Extruded rubber products

  • Moulding compoundsSolid extruded rubber – Our range of extruded rubber products are available in various types of rubber. We supply solid extruded rubber formed by pressing uncured material through a die in order to create a profile. Depending on the material, it will then be cured in an autoclave or infra-red chamber. Formers or jigs may be required to hold the shape of the product until it is fully cured.
  • Sponge extruded rubber – Our extruded rubber products are also available in sponge extruded rubber, which is formed by pressing uncured material through a die in order to create a profile. Similar to our solid extruded rubber, it is then cured in an autoclave or infra-red chamber, depending on the material. Again, formers or jigs may be required to hold the shape of the product until it is fully cured. Fabric coverings may be applied as part of the extrusion process.

Sheet moulding compound products

  • Moulding compoundSheet moulding and injection moulding compounds are made using rubber mixes or “recipes” in their uncured form. Usually the cure system is added and ready for the thermoset reaction to take place when correctly processed.
  • Extruding compound – Extruding compounds are similar to moulding compounds in the sense that they are made of rubber mixes or recipes in their uncured form, but with different compounding to reflect the demands of the extrusion process. This often requires a high quality material in order for it to be successful.

Thick and thin rubber sheets

  • Solid sheeting – Our fully cured solid sheeting is available in a variety of standard thicknesses (as we are able to provide both thick and thin rubber sheets), widths, lengths and materials. The surface finish may be a smooth ‘plate’ finish, or a ‘cloth’ finish, where a transfer layer of cloth leaves an impression on the surface.
  • Rubber insertion sheeting – is fully cured solid rubber. However, it has one or multiple layers of fabric ‘inserted’ within the cross section of the material to give a higher tear strength material. Flat ‘Diaphragm Sheet’ is of this construction, as is Conveyor Belting and Gasket Insertion.
  • Sponge sheetingSponge sheeting is manufactured in such a way as to have a foaming agent form bubbles during the curing process. This provides a much more compliant product. If the resulting cells are sealed from each other, this creates a closed cell foam material. However, if they interconnect, an ‘open cell’ or ‘reticulated’ foam product will be formed, which will pass liquids and gasses.
  • EMI-RFI Sheeting – Our EMI-RFI sheeting consists of only materials with electrical conductivity that can act as a continuous electrical interface across a gasket joint, either by virtue of having metal filaments inserted in the material, or metal particles in a rubber binding matrix. This can be used for ensuring shielding or delicate electronic components are contained in enclosures where access is required and a gasket forms the seal.
  • Billet – Our billet material is a tube or bar of solid rubber or engineering plastic, suitable for machining on CNC or manual equipment.

Adhesives and sealants

  • Adhesive materials – Our adhesive materials are suitable for bonding like or dissimilar materials together, with different mechanical and chemical resistance properties. With careful selection and preparation, our materials will achieve consistent success.
  • Mastic sealant – Our mastic sealant range here at Martin’s Rubber consists of a range of materials suitable for filling gaps and other adhesive purposes. The mechanical and chemical resistance properties can vary, therefore careful selection and preparation is essential for consistent success.
  • Self-adhesive backing – We supply a wide range of self-adhesive backing consisting of various materials suitable for bonding like or dissimilar materials together. With different mechanical and chemical resistance properties, careful selection and preparation is essential for consistent success. Our backing comes in a thin layer on a backing film and can be applied to a wide variety of materials. Due care must be taken when considering application to solid rubbers, as the process waxes present can migrate to the surface of the rubber over time, breaking down the bond of the self-adhesive backing.
