Compounds

Most rubber compounds have been formulated to meet the requirements of Australian and International standards with certification provided on request.

Glazing compounds are formulated to BS 4255 for EPDM gaskets and setting blocks (as specified in AS 1288 Glazing Standard), ASTM C864 for Neoprene gaskets and ASTM C1115 for silicone gaskets.

We have water potable EPDM approved by Sydney Water and compound approval from the Roads and Traffic Authority for bearing rubbers.

                      Rubber Properties Table

EPDM - good general purpose rubber. Excellent ozone resistance making it appropriate for outdoor applications.

EPDM SCR (Silicone compatible) - used in glazing applications as it is compatible with silicone sealants.

Natural Rubber - good general purpose rubber where abrasion resistance or high tear strength are required. Can be compounded to achieve ozone resistance but is not oil resistant.

Neoprene (Chloroprene) - versatile rubber with good flame resistance making it appropriate for applications such as elevator door seals and high rise commercial window gaskets.

Nitrile - Often used in applications involving fuel and oil.

Chloro Butyl - good resistance to atmospheric aging, oxidising chemicals, acids and oils.

Silicone - excellent ozone and UV resistance for long term glazing gaskets. Excellent heat resistance for use in oven door seals.
