Application Advice/Typical Applications

SYNTHOMER X 90Y20 is used mainly to manufacture dipped goods and should be vulcanized. These articles have a good resistance to oil, petrol, greases and plasticizers. Products are charactirized by good film-formation, even at very thin films and a balanced relationship of tensile strength and film softness. Unsupported gloves are manufactured by the "Coagulant Process". After the mould or former has been dipped in the latex compound, the coagulate (or film) that adheres to it is washed thoroughly with warm water (40°C), dried at 80°C and vulcanized at 100°C-130°C. Supported gloves are produced by dipping the fabric glove, which is slipped onto a suitably sized former, into a thickened compound, dried and vulcanized at 100°C-130°C. On request we will be pleased to provide you with typical formulations for your guidance.

SYNTHOMER X 90Y20 is protected against bacterial attack during storage. In the manufacture of finished products, the material has to be retreated, as usual, with suitable agents to give enhanced preservation.

Shipping and Storage

SYNTHOMER X 90Y20 is supplied in road tankers or in non-returnable plastics drums secured by a lid with clamping ring or in non-returnable palletized bulk containers (net weight 1,000 kg). SYNTHOMER X 90Y20 has to be stored protected from frost and at temperatures not higher than +40°C. Storage at temperatures between +5 and +30°C is recommendable. Storage at temperatures over +30°C for longer periods should be avoided. Care must be taken to ensure that drums and storage containers are tightly closed. During processing, storage and transport of the product contact with metals unprotected against corrosion (likewise non ferrous metals) has to be avoided. When storage correctly the product has a shelf life of 6 months.
