Model No.: TECAFORM® HPV13 brown homopolymer acetal
Brand: TECAFORM
| Selling Units | : | Kilogram |
| Package Type | : | Export package |
TECAFORM® HPV13 is a brown homopolymer Acetal with an internal PTFE lubricant. Its low coefficient of friction, excellent PV values, toughness, wear resistance, and machinability make it an exceptional material for use in many industrial and military components with moving parts. Additionally, TECAFORM® HPV13 has superior chemical resistance and flexural fatigue properties, as well as low moisture absorption associated with acetal materials

Key Properties
Lower cost alternative to Delrin AF blend
No stick slip
Low coefficient of friction
Good dimensional stability
Superior wear resistance
Superior resistance to repeated impacts and creep
Self-lubricating
The use of TECAFORM™ HPV 13 can eliminate costly lubricants, reduce maintenance costs and product contamination.
Excellent machinability
Complies with FDA regulation 21CFR 177.2480 and may be used in contact with food up to 150 F on a repeated use basis, except those foods containing more than 15% alcohol. Delrin® AF does not.
Limitations
Wear Resistance in Dry Environments
Poor Resistance to Strong Acids and Alkalies
Slightly Lower Mechanical Properties than Homopolymer Acetal
Applications
Bushings & Bearings
Thrust Washers
Wear Components
Wear Strips
