Glassfibre Reinforcing Materials

CHOPPED STRAND GLASFIBRE MAT
We offer a range of 3 general purpose chopped strand glassfibre mats which are all suitable for hand laminating in open moulds.
 

CHOPPED STRAND GLASFIBRE MAT M5
M5 chopped strand mat is made from E-glass chopped strands. They are held together by an emulsion binder, soluble in styrene, which gives M5 an excellent compatability with UP resins. It is designed for general purpose use in a wide range of applications, offering medium impregnation speed and good conformability to mould shape.

CHOPPED STRAND GLASFIBRE MAT MI23/POWDER BOUND
M123 chopped strand mat is made from E-glass chopped strands, held together by a powder binder, soluble in styrene. It is designed for easy impregnation and good translucency. It is particularly recommended for translucent mouldings where the best effects are obtained by using a polyester resin with matching refractive index.

GLASFIBRE ROVINGS FOR SPRAY-UP P207
P207 is an E-glass continuous roving which has a sizing system with a silane coupling agent. It is designed for general purpose applications in a wide range of sectors and provides good chopping behaviour and optimal overall performance for spray-up applications.

CHOPPED GLASSFIBRE STRANDS
Chopped glassfibre strands are a general purpose product, suitable either for polyester or phenolic resin or epoxy reinforcement. It offers good dimensions and impregnation characteristics and high mechanical properties in injection on compression moulded parts. It can also be mixed with a resin to form a “dough” for reinforcement of intricate cavities.

Storage
All glassfibre mats and roving should be stored dry and in its original packaging. The best conditions are temperature between 10 and 35°C and at a relative humidity between 35 and 85%.
If the product is stored at low temperature (below 15°C) it is advisable to condition it in the workshop, for at least 24 hours before use, to prevent condensation.
The product can be stacked one plus one but it is recommended to use a plywood plate between the two pallets in order not to damage the lower pallet.

SURFACING TISSUE M524-664
Surfacing tissue is made from very fine glassfibres which are chemically-resistant in both acid and alkaline environments. It is bound using a modified styrene-acrylic co-polymer which is formulated to be compatible with all commonly used resin systems. It is used to produce a resin-rich surface as either a gelcoat replacement or a mask for coarse glassfibres.

GLASS TAPES
A plain-weave glassfibre tape woven from continuous filament yarns. Used for winding, wrapping and local reinforcements.

WOVEN ROVINGS
Woven roving is a plain weave glassfibre fabric, which has a surface dressing rendering it suitable for use with polyester or epoxy resins.
Woven ravings are often used in composite laminates with chopped strand mat, the latter being used to increase the bulk of the laminate. Rovings wet out far more quickly than certain types of mat, pick up a lower percentage of resin, approx. 50% glass, 50% resin, and have far higher physical properties. A roving laminate, thickness for thickness is much stronger than an all mat laminate, and a thinner, lighter and less expensive laminate can often be made.
We stock woven ravings normally in 300g and 600grm/ m² but due to the variety of weights and widths, please contact us with your requirements.

GRP FLAT-ROOFING TRIMS
Due to the ever increasing popularity of GRP for flat roofing we offer a range of GRP roof trims to complement our ranges of resin and glassfibre. The trims are light grey in colour, U.V. stabilised, 550g/m², in 3M lengths and fire retardant to BS476 part 3, We show below a representative selection of the most popular sections but many others are available. Please request further details.
