PRODUCT MATERIALS GLOSSARY

The choice of material for any component incorporated into the design and manufacture of Safe-T-Products is vital to ensure the best possible outcome for functional integrity, reliability and longevity, particularly in harsh environments like Western Australia’s Pilbara region. Each material has been extensively researched and field tested prior to being utilised in any device, equipment or hardware. As part of Safe-T-Products’s continuous improvement practice, the design team continues to test new and/or improved materials on the market against currently employed materials.
As a result, Safe-T-Product is the only manufacturer in Australia supplying a range of static dissipation polymer safety devices, which can be installed in explosive atmosphere zones.

UV STABLE POLYURETHANE COATED LIQUID CRYSTAL POLYMER (LCP) – VECTRAN™

The characteristics of liquid crystal polymer (LCP) make it an ideal choice for wire rope in demanding situations where extra strength, chemical resistance, minimal moisture absorption, dimensional stability, cut/shearing resistance, abrasion resistance, heat resistance, vibration damping, shock absorption and electrical insulation is desirable. The rope is made from multifilament melt spun yarn and is encased in UV stable red polyurethane to withstand cracking and/or deterioration even in regions with extreme solar UV intensity. 

The red coating also ensures compliance with Machinery Standards AS 4024.1604-2006 Clause 5.4.6 Actuator Colour stating “The actuator of the emergency stop device SHALL be coloured red.”.

UV STABLE POLYURETHANE COATED STAINLESS STEEL

Construction grade stainless steel wire is a good and inexpensive choice for wire rope. The stainless steel rope is encased in UV stable red polyurethane to withstand cracking and/or deterioration even in regions with extreme solar UV intensity The red coating also ensures compliance with Machinery Standards AS 4024.1604-2006 Clause 5.4.6 Actuator Colour stating “The actuator of the emergency stop device SHALL be coloured red.”.

ELECTRO POLISHED STAINLESS STEEL

When using stainless steel in environments with elevated moisture in the air, it is imperative that the stainless steel is protected from rust through electro polishing. While 316 stainless steel is more resistant to rust than other grades, it is not entirely immune from it. Miniscule iron particles in the air accumulate in the ‘dimples’ of stainless steel and start the rusting process. Electro polishing removes these microscopic surface imperfections in the steel minimising the potential for rust.

Even though stainless steel components within our devices are not exposed to elevated moisture in the air, electro polishing stainless steel serves another purpose. Because the electro polishing process maximises the smoothness of the surface, a tighter seal around stainless steel components is achieved where needed and makes for smoother operation of moving components. Both are important for solid functional operation.

All our enclosures are manufactured from 2 mm 316 stainless steel and electro polished to achive the best IP rating possible.  

POLYBUTYLENE TEREPHTHALATE (PBT)/POLYCARBONATE (PC) ENCLOSURE

Our most common enclosure is made from PC/PBT. The material has high impact strength and is resistant to chemicals. In conjunction with the plastic manufacturer, Safe-T-Product developed a mix of flame retardant additive, UV stabiliser and colour pigment for flame retardant distribution without impacting on the inherent strength of the material itself.
