Arnite®

Mechanical marvel

Arnite® has excellent mechanical properties. It’s strong with excellent stiffness and outstanding creep properties even at high temperatures. This material is also extremely durable with very low wear loss and co-efficient of friction.

Glass-fiber reinforced Arnite has excellent strength and stiffness. Because of its high strength, the material is ideal for demanding applications needing close tolerance, such as break booster valve bodies.

Arnite A GF50 offers highest strength and stiffness at ambient conditions and shows no effect of moisture.

For maximum impact strength - ideal for applications requiring extra toughness – we offer impact-modified Arnite grades as well as glass-fiber reinforced grades with significantly increased notched impact strength (both Arnite A and Arnite T).

Creep resistance and durability

Creep resistance (low deformation under load) – the ability of plastics to maintain their shape under sustained stress – it is a critical mechanical property and one that Arnite meets very well which makes it suitable for various automotive applications, which could replace metal parts.

Resistance to high frequency cyclic loading

In general, geometry, residual stress, corrosion property, internal defects, temperature, environment could reduce fatigue life of parts. Arnite A has excellent temperature performance withstanding cyclic loadings.

Arnite AV2 390 XT shows excellent fatigue performance over a wide temperature range.

Furthermore, both Arnite T and Arnite A have good resistance to wear loss and low frictional coefficients, ideal for applications where sliding forces are involved. In fact, the outstanding frictional response of polyester to rubbing contact with other materials is what sets Arnite T apart from other thermoplastics.

Real-time frictional measurements comparing PA6 to Arnite T show excellent frictional consistency. For applications that need smooth actuation as well as low overall frictional effort, Arnite T is the ideal choice. Arnite A, on the other hand, is used in various applications where extreme wear requirements are important – for example where the static friction coefficient should be as low as the dynamic one.
