Hylomar PL32

Hylomar PL32 Aerograde is a highly engineered, polyester-urethane based non-setting and non-hardening gasketing compound, for use in the aeronautical industry.

Hylomar Aerograde was developed in conjunction with Rolls Royce - Aerospace Division for sealing joints in jet turbine engines. Hylomar Aero Grade can operate at temperatures from approximately -50C to + 250C.

Hylomar Aerograde is resistant to air turbine and piston engine combustion products; water glycol/water and methanol/water mixtures; petroleum and synthetic diester lubricating oils; gasolines and kerosene fluids (both Avtur and Avcat) and some fluorocarbon refrigerants.

It is harmless to joint face materials. Traces of volatiles produced at elevated temperatures do not stain copper or silver, therefore, Hylomar Aerograde is suitable for joints and threads in close proximity to switch mechanisms etc.

It is equally suitable for use as a gasket dressing and for metal to metal application. Hylomar Aerograde has been tested, approved and is in use by, National Power/ Powergen. 15/53/181. NCB Vocab No 13.82.0414.0303.16423. British Rail catalogue No 9/2/31138 & 31140. MOD A.F.S. 147 D.T.D. 900/4586B. Hylomar Aerograde also meets the BASEEFA requirements for flame proof joints.
