TECANYL® VH2 Aerospace-Grade PPE Thermoplastic

TECANYL® VH2 from our material partner Ensinger, Inc. is an aerospace-grade PPE (polyphenylene ether) thermoplastic with outstanding toughness, dimensional stability, and flammability characteristics. It is often specified for aircraft applications where tight dimensional tolerances and toughness and durability are required.

TECANYL® VH2 is frequently used instead of aluminum or thermoset composite materials to achieve weight savings for aircraft interior applications with light mechanical loads. Unlike thermoset composites, TECANYL® VH2 can be recycled, resulting in more environmentally sustainable aircraft designs.

TECANYL® VH2 passes stringent FAR 25.853 testing for use in aircraft systems. TECANYL® VH2 Black

TECANYL® VH2 has a low rate of thermal expansion and it has low absorption of atmospheric moisture. This allows parts made from TECANYL® VH2 to be machined to close dimensional tolerances. Some traditional aerospace grade thermoplastics such as fire retardant nylons exhibit significant dimensional changes due to swelling from moisture absorption and high rates of thermal expansion. The graph below shows the low thermal expansion rate and the low moisture absorption of TECANYL® VH2 compared with other polymers.

Graph comparing TECANYL® VH2 to other polymers, highlighting its low thermal expansion rate and low atmospheric moisture absorption. These properties allow TECANYL® VH2 to be machined to close dimensional tolerances. In contrast, traditional aerospace-grade thermoplastics, such as fire-retardant nylons, show higher thermal expansion and increased dimensional changes due to moisture absorption

TECANYL® VH2 also has outstanding toughness and impact strength compared with many other engineering plastics. This makes it an outstanding choice for aircraft applications where toughness and durability are required. Other engineering polymers may be prone to cracking from vibration or impact during use. The graph below shows the impact resistance of TECANYL® VH2 compared with other thermoplastic materials.
