Glass Based Laminates - SRBG
Glass gives you the properties to perform...
Out all the laminate grades available in our portfolio, glass reinforced laminate brings better mechanical properties to your product. This is in part a result of fibre density. Glass fibres are significantly denser than cellulose (cotton or paper), giving the laminates a density of around 1.8 to 2 g/cm3. Other properties such as flammability, temperature stability, electrical, water absorption and insulation resistance are determined by the resin system used.
The mechanical and the electrical properties of all of epoxy grades are broadly similar at normal temperature.
Our Grades include:
- G10 - Good Mechanical Properties a temperatures up to 130°C
- B36 - Retains a high proportion of mechanical properties at temperatures of up to 155°C
- B38 (FR) - Our flame retardant epoxy with good electrical and mechanical properties
- B48 - Retains a high proportion of mechanical properties at temperatures of up to 180°C
Phenolic glass (LUL SE970)
Phenolic glass has good mechanical and electrical properties, though generally these are lower than the properties of epoxy grades. It does however, possess a degree of flame retardancy. Its relatively low smoke emission and toxicity help make it ideal for closed situations such as underground, aerospace or enclosed switchgear.
Silicone glass laminate (LUL SE970)
Silicone glass laminates have low dielectric loss. With power factors as low as 3.8 – 4, and with very low relative permittivity, the material is suitable for use in high frequency applications such as microwaves and transmission antennas.
Our Grade B32 exhibits very low smoke toxicity and a high degree of flame resistance as well as temperature resistance to 180° – 200°C (or intermittently much higher). This makes it suitable for use in closed environments such as underground transportation and harsh environments such as furnace insulation.
Polyimide resins exhibit high mechanical strength and good temperature resistance. Polyimide laminates such as our grade B34 are often used at continuous temperatures of up to 180° or 200°C and intermittently at temperatures as high as 250°C and consistently maintains its high mechanical strength.
Glass reinforced laminates are ideal for:
- Electro mechanical components, washers, gaskets, bushes and tubes
- Aerospace – fairleads, clamping blocks, tubes & gaskets
- Electrical switchgear supports, packing, blocks, pads, clamps and sleeves
- Marine – Bearings, pulleys, fittings and mechanical components
- Transformer packing, blocks & mounts
- Rail, Transport and Underground Sector use
- General Engineering machined component parts
B30 and B32 are London Underground Limited approved making them suitable for London Underground use
