Ways for FRP cooling towers manufacturers to play around with design to suit needs of clients

FRP is an interesting material which allows manufacturers to play around with its shape and achieve desired results. Majority of the products are produced in conventional designs and profiles but it has adjustable mechanical properties which are leveraged by cooling tower manufacturers in Delhi.

To get into the details, most manufacturers use four types of reinforcement in FRP namely E-Glass, Aramid, S- Glass and Carbon. All these have different qualities like density, tensile strength, tensile modulus and % elongation to break- E Glass has the maximum density (0.094 lbs/in³), S Glass has maximum Tensile strength (665,000 psi) and E Glass has more tensile modulus 10.5 (106 psi) and elongation to break (4.8%). For these reasons E Glass is the most commonly used variant as reinforcement in FRP cooling towers. 

Further there are Two main Types of Reinforcement – continuous strand mat and continuous strand roving. The most economic style is continuous strand mat where a resin is used as a binder for glass fibres. Layered with roving, these are mats of intertwined glass fibres and the ratio of mat to roving is important for manufacturers as it decides the longitudinal and transverse strengths.  In continuous strand roving- the key is number of roving used and their location as both these affect the product’s performance. Roving is the one behind tensile strength of structure and its pultrusion can make the reinforcement look closer to the surface of product. Resins are the veils used on surface of the product to distance the reinforcement which otherwise influences corrosion resistance etc.  Commonly used materials for resins are polyster, epoxy and vinylsester. Epoxy is the one which is more popular and add considerable strength to the structure and commonly are teamed with E Glass.

Cooling tower manufacturers play around with FRP to suit their needs and add different chemicals to augment its properties like aluminium silicate for finish and insulation, calcium carbonate for opacity and cost effectiveness etc. the material offers lot of opportunities and its flexibility makes it the most popular material for cooling tower construction.
