Heat Resistant Low Friction Plastic for Hard Metals

Grade
  • NIXAM　2
  • NIXAM　512B
Function Versus hard metal heat-resistant sliding property
Characteristics
  • Heat resistance (180 ° C) using PPS resin
  • Chemical resistance to acid, alkali, air conditioner refrigerant
  • By adding a sliding aid, we enable better sliding properties compared to the conventional PPS
  • Resistance to: wear, refrigerant, oil and high rigidity
  • Replacement of metal parts and weight reduction
  • NIXAM 2: High rigidity material with excellent sliding characteristics. Ideal for metal substitution
  • NIXAM 512B: High fluidity material with sliding properties and thin-walled parts.
Performance We carried out a sliding evaluation following the evaluation conditions stated on the graphic below.

We found that NIXAM 2 and NIXAM 512 B have little to none wear.

We also confirmed that the wear for the PPS general sliding conditions was 70 times worse than the NIXAM products that underwent the same testing conditions.
Applications Oil pump parts, tip seals, etc.

One point comment: Compression principle of scroll compressor

The scroll compressor consists of 3 scrolls swirling at different tempos (1 → 2 → 3 → 4) to keep the  air sucked between the fixed scroll and the orbiting scrolls, seeking to move the volume of the sucked air towards the center.

Once the air has reached a certain pressure, it is pushed out from the discharge port. The seal tip provides tightness between the swiveling, preventing the fixed scroll from touching the swiveling, and preventing potential damage from the fixed scroll.
