What are Polyester, Vinylester and Carbon Ceramic Composite?
A polyester is a polymer that consists of a chain of ester compounds. These polyesters are formed in one of two ways: firstly, via a polycondensation reaction between dicarbonic acid and a diol. And secondly, via a polycondensation reaction between a large number of molecules and a dicarbonic acid/alcohol group. The polyester known as polyethylene (PET), for example, is produced from glycol and terephthalic acid, and is commonly used to produce soft drink bottles and clothes.
Polyesters can be either thermoplastic (i.e. they melt under the influence of heat) or a thermosetting plastic (i.e they harden under the influence of a chemical reaction). Thermosetting polyester is a liquid mixture of unsaturated polyester and styrene, as both components react under the influence of a hardening agent to form a hard plastic.
Vinylester is a resin produced through esterifying an epoxy resin with an unsaturated monocarbonic acid. The resulting product of this 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 tend to be greater than those of polyester. Therefore, the material is frequently used in the marine industry, thanks to its ability to resist corrosion and withstand water absorption.
Fibre-Reinforced Plastics / Composite Material
‘Composite material’ is generally used for fibre-reinforced plastics and is defined as: a material composed of several clearly distinguishable materials where the properties of the composite material are better than those of each individual component.
Resins (like phenol, epoxy, polyester and Vinylester) are used to bond the filling materials (i.e. carbon fibre, glass fibres, aramide fibres, textile, pulverised stone) either with each other, or to the core itself. Some of the more well-known applications include yachts, rowing boats and Monoblock pools.

How are Compass pools manufactured?
Each Compass Monoblock pool is manufactured according to the Australian patent PN 1690, which forms the basis of the insurance policy. Every one of our pools undergoes a variety of production phases which take place in specially temperature and air-conditioned rooms.
In total, six glass fibre-reinforced layers of composite are laminated onto an open mould to produce a solid, chemically resistant basin. During the first phase of this process, the foundation is laid for the pool’s major properties – chemical resistance, colourfastness, and scratch resistance.
