Polyester

A polyester is a polymer that consists of a chain of ester compounds. Polyesters are formed by a polycondensation reaction between dicarbonic acid and a diol or by a polycondensation reaction between a large number of molecules and a dicarbonic acid and an alcohol group.

When, for example, a polyester is produced from glycol and terephthalic acid, that produces polyester polyethylene (PET). PET is used for making soft drink bottles and for clothes.

Polyester can be either a thermoplastic (melting under the influence of heat) or a thermosetting plastic (hardens under the influence of a chemical reaction),

Thermosetting polyester is a liquid mixture of unsaturated polyester and styrene. These two components can react under the influence of a hardening agent (a peroxide) to form a hard plastic.

Vinylester

Vinylester is a resin produced by the esterification of an epoxy resin with an unsaturated monocarbonic acid. The product of the reaction is then dissolved in a reactive solvent, such as styrene, up to a 35-40 percent content on a weight basis.

Vinylester can be used as an alternative for polyester in a matrix of composite materials. The properties and strength of Vinylester are superior to those of polyester. It is therefore frequently used in the marine industry, due to the better corrosive resistance and the ability to withstand water absorption better.

Fibre-reinforced plastics / Composite Material

The more generic term ‘composite material’ is generally used for fibre-reinforced plastics. The definition of a composite material is: A material composed of several clearly distinguishable materials where the properties of the composite material are better than those of each individual component.

Resins (such as epoxy, polyester, phenol and Vinylester) are used as a bonding material to make the filling materials (glass fibres, aramide fibres, carbon fibre, textile, pulverised stone) adhere to one another or to the core (with sandwich constructions, a honeycomb structure of, for example, aluminium, phenol foam, balsawood) or to make the rougher main material (PVC, polystyrene, quartz, stone) bond together.

Well-know applications are yachts, rowing boats and monoblock pools.

How are Compass pools manufactured?

Every Compass monoblock pool is manufactured according to the Australian patent PN 1690, the basis for the insurance policy. The pool undergoes various production phases in specially conditioned rooms where the temperature and atmospheric humidity are controlled.

A total of six glass fibre-reinforced layers of composite are laminated onto an open mould to produce a solid, chemically resistant basin.

In the first phase, the foundation is laid for the colourfastness, chemical resistance and scratch resistance.
