Heat Resistant Low Friction Plastic for Hard Metals

Grade
  • NIXAM 2
  • NIXAM 512B
Function Versus hard metal heat-resistant sliding property
Characteristics
  • Excellent heat resistance (180 ° C) based on PPS resin
  • Excellent chemical resistance such as acid, alkali, air conditioner refrigerant
  • By adding a sliding aid, it has better sliding properties than conventional PPS
  • Wear resistance, refrigerant resistance, oil resistance, high rigidity
  • Replacement of metal parts, weight reduction possible
  • NIXAM 2: High rigidity material with excellent sliding characteristics. Ideal for metal substitution
  • NIXAM 512 B: High fluidity material with excellent sliding properties. Thin-walled parts
Performance

Sliding evaluation was carried out under the following evaluation conditions and the difference in wear amount was shown.
We found that NIXAM 2 and NIXAM 512 B have very little wear.
In addition, we confirmed that wear of about 70 times of NIXAM was observed when evaluating the glass-filled PPS of general sliding grade under similar conditions.

Applications Oil pump parts, tip seals, etc.

One point comment: Compression principle of scroll compressor

The main parts of the scroll compressor consist of orbiting scroll and fixed scroll. As the orbiting scroll swirls from 1 → 2 → 3 → 4, air is sucked in between the fixed scroll and the orbiting scroll, and the volume gradually decreases towards the center. When the air reaches a certain high pressure state, it is pushed out from the discharge port. The tip seal keeps high airtightness of the air compression space between the swiveling / fixed scroll and avoids contact with the swiveling / fixed scroll, and prevents damage.
