Phenolic Temperature Range

Phenolic foam is available from 20mm to 50mm thick.

Phenolic temperature range. When hybridised with epoxy and phenolic resins the resulting ternary systems have glass transition temperatures in excess of 490 f 250 c. Mineral wool ceramic fiber. The density range is from 35 to 200 kg m normal density. Phenolic composites are largely used in the aircraft interior and mass transit industries buses railways with interest increasing in marine applications.

Low high o c o f o c o f calcium silicate 18. Both have high temperature stability up to 300 350 c high water and chemical stability. The self ignition temperature of the phenolic resin is approximately 600 c and the limiting oxygen index loi is in the range of 40 49. These are made by the reaction of phenols formaldehyde and primary amines which at elevated temperatures 400 f 200 c undergo ring opening polymerisation forming polybenzoxazine thermoset networks.

Phenolic plastics are composites made from the combining of phenol aldehyde and formaldehyde and filler materials. Phenolic resins are often dark colored from yellow to dark red and have an excellent price performance profile. Phenolic resins are divided into two different types novolacs and resoles. Nylon reinforced phenolic nema n 1 per mil i 24768 9 type npg superior electrical properties under humid conditions fungus resistant continuous operating temperature of 160 f.

Phenolic materials are available in sheets tubes rods blocks as well as specified shapes. The approximate maximum continuous operating temperature is 120ºc. Continuous operating temperature 250 f. Recommended for intricate high strength parts.
