Sustamid 6 FT (PA6) meets the relevant requirements of rail vehicle standard DIN EN 45545-2:2013. Sustamid 6 FT is an extruded semi-finished product, allowing finished parts of large dimensions to be manufactured in small quantities – such as cable clamps for rail vehicles. Sustamid is free of halogen and phosphorus, has good slide and wear behaviour, and is flame retardant.

PVC is an all-round plastic with a wide range of advantageous properties, including self-extinguishing and good chemical resistance, as well as good mechanical and tensile strength properties. Rigid PVC is extremely strong and exceptionally hard, has low water absorption and exhibits good weather resistant properties.

PVC is easily machined, allowing close tolerances without great difficulty. This material is also readily available and very cost effective, making it an ideal choice for several industries.

Available in a range of grades – Nylon 6, Nylon 66

Nylon 6 has remarkable chemical resistance abilities and excellent insulating qualities. Additionally, Nylon 6 has a strong combination of mechanical strength and damping qualities, along with very good creep and abrasion resistance. These factors make Nylon 6 an excellent “general purpose” grade for mechanical construction and maintenance applications.

With its good wear resistance and a service life up to 10 times longer than standard Nylons, the material is a favoured solution for bearings, gears, wear pads, pulleys, sheaves, bushings, valve seats, and seals.

Nylon 66 has greater mechanical strength, stiffness, creep resistance and heat and wear resistance than its counterpart, Nylon 6. However, these positive characteristics are at the expense of impact strength and mechanical dampening, which are two features found to be stronger in nylon 6.

Additionally, Nylon 66 can withstand high energy radiation as well as being an excellent insulator, making it a key product in the engineering and technology industries.

Acetal is a high strength, low friction engineering plastic available in two grades – homopolymer and copolymer, both of which have excellent wear properties in wet and dry environments and good abrasion and electrical resistance. Acetal plastic is chemically resistant to hydrocarbons, solvents, and neutral chemicals, and is easy to machine, making it an outstanding choice of material for applications that require complex, tight tolerances.

While Acetal copolymer and Acetal homopolymer are generally interchangeable since their properties are within 10% of each other, each material does offer its own unique strengths:

Acetal - Homopolymer

PTFE has very good resistance to low and high temperatures, has a low friction coefficient, and is available in various grades, known as Virgin PTFE, 25% carbon filled PTFE and 25% glass filled PTFE. PTFE is inert to practically all chemicals and has excellent non-stick properties. It is relatively soft, which is ideal for sealing applications but not good for mechanical strength in threads.
