6.1 Increased Use of Thermoplastic Rubbers and High Performance Rubbers

A search of any major abstract database reveals the extent to which new thermoplastic rubbers are entering the food contact market. The attraction of these materials is that they are relatively simple compared to conventional rubbers, which means that they contain less potential migrants overall, and none of those which have received the closest scrutiny in recent years (e.g., nitrosatables and primary aromatic amines). In the main they have entered the market in one of two ways: as replacements for existing rubbers, and as replacements for other food contact materials. There are a number of examples of TPEs replacing vulcanised rubbers in the literature. For example, a co-polyester based TPE with high temperature resistance has been developed to replace rubbers such as silicone (11). A recent development is the manufacture of polyurethane TPE food contact gloves as an alternative to natural rubber or nitrile rubber gloves (62), and there is the continuing utilisation of thermoplastic vulcanisates such as Santoprene as an alternative to conventional vulcanisates (38). For the manufacture of babies teats and dummies, high performance clear TPEs based on styrene-block copolymers are competing with silicone rubber for this application (54).

An example of TPEs replacing other food contact materials is the use of SEBS block copolymers to manufacture synthetic corks for use in wine bottles instead of natural cork (99). This trend has been assisted in recent years with the continued proliferation of thermoplastic vulcanisates (TPVs). These materials...

Products & Services
Rubber Sheets and Films

Rubber sheets and films are flat expanses of conformable rubber or elastomeric material that can be used for vibration dampening, equipment protection and isolation, and many other applications.

Elastomer and Rubber Shapes
Elastomers and rubber shapes are natural or synthetic  polymers that exhibit elastic properties and can be formed into finished or semi-finished stock.  These amorphous polymers are usually thermosets, but are also available as thermoplastics. Elastic polymer (elastomer) and  rubber shapes are available in different forms and sizes, and often use filler materials.
Rubber Tubing
Rubber tubing is used in flow lines for fluids and gases in a variety of hydraulic, pneumatic, process, medical, and specialty applications.
Rubber Adhesives and Sealants
Rubber adhesives and sealants are highly flexible, natural or synthetic materials that are used to join components or fill gaps between seams or on surfaces.
Adhesive Tapes
Adhesive tapes are used to assemble materials or parts together using a sticky chemical bond. Adhesive tapes are made by coating a backing or carrier (paper, plastic film, cloth, foam or foil) with an adhesive on a web or roll coater.
