Unsaturated Polyester Resins
 

GPK has a comprehensive offering of UPR’s including orthophthalates, isophthalates, terephthalates and vinyl esters. These are highly effective resins for FRP composites because they have excellent mechanical and corrosion resistance properties, and are lightweight. Specialty UPRs are approved by Lloyds Register of Shipping (LRS) and Water Regulations Advisory Scheme (WRAS), UK under BS 6920 for potable water application.

Reinforced plastic laminates for marine construction, bath ware and shower stalls.
Electrical components.

Tanks.
Ducts.
Sheet molding compounds (SMC) for the automobile and transportation industries.
 

High Strength
On a weight for weight basis Kemrock Glassfibre Reinforced Polymer Composites are as much as seven times stronger than steel.

Lightweight
Kemrock Glassfibre Reinforced Polymer Composites can be as much as one quarter the weight of ductile iron and a tenth the weight of concrete.

Corrosion Resistance
Selecting the appropriate resin matrix enables Kemrock Glassfibre Reinforced Polymer Composites to resist aggressive effluents soils and most common industrial chemicals.

Ease of handling & installation
Their lightweight & high strength enables Kemrock Glassfibre Reinforced Polymer Composites to be readily transported and handled. They can be worked on-site with ordinary hand tools, & jointing is a simple semi-skilled operation.

Longevity
Kemrock Glassfibire Reinforced Polymer Composites are durable, virtually maintenance free and provide long life solutions offering resistance to aging, long term creep and corrosion.
