GB 2 340 125 A

Patents on composite materials resulted in the discovery in 1980 of ways of preventing highly combustible materials from exploding into flames during any fire.

Pat 2340125

Expanded polystyrene beads or reclaimed expanded polystyrene, coated with certain coatings were shown not to explode into fires. These materials are made from rigid hard matrixes. This technology provided very low density materials that could be used as fire retardant barriers and can be used to make low weight ceiling tiles, partitioning, fire retardant linings to replace plasterboard, coating of oil pipe installations etc and conforms to British Standards 476 Part 6, Part 7 and Building Regulations Class 1 material. These composites can be termed smart materials because they change their composition in any heat stressed areas from BS 476 Part 6 & 7, BR Class 1, to BS 476 Part 6 & 7, BR Class 0. The material is capable of withstanding temperatures of 2000c and because fire spread is so low, only the area subjected to flames reacts to heat. These materials have high heat insulating properties, (0.05w/m/K)

Other materials can be similarly treated. The material composite using expanded polystyrene, can be used to manufacture low density garden furniture, paving slabs for the DIY market, cladding slabs etc. Essential to the miscibility of the very low density expanded polystyrene and the high density cement and aggregates, is the researched and tested factor, essential to the complete homogeneity achieved in these mixes.

Extensive range of uses with specialized applications in the ceramics industry. As an example only, the material can be made to line firing kilns and kiln furniture, so that a far smaller amount of energy is required to bring kilns to full working temperatures.

The availability of Styrocrete has facilitated the design of the most efficient fire stop system available for service penetrations. The design separates the services and coats the individual services with Styrocrete. The concept offers a standardized box that is designed to fit with standard building materials.

Pat 2371931

This is the only commercially available system for manufacturing building blocks that will guarantee to withstand extended fires. Ideal for lining lift shafts, forming partitions, building safety corridors, high rise buildings, ministry of defence applications, petrochemical industry, commercial, industrial and home use. The composite is designed to withstand fires for many days and is ideal for high rise buildings.

Renders and "plaster board" type sheet materials can be made from this permanent fire retardant composite.

Tested to 1000 degrees (Celsius) for a continuing period of 24 hours.

Pat 2340125

An innovative extension to the same principals provides low density, fire retardant materials that have a flexible matrix. These materials are suitable for fire retardant applications in situation where the material needs to be flexible during normal use. All such materials have electrical and heat insulating properties (0.05wats/m/K).

This composite can be sued to provide non degradable flotation technology so that a whole range of unsinkable maritime vessels can be made that can guarantee that they will not sink even if they split in two. This technology is particularly suitable for the leisure industry and can provide a large number of associated maritime accessories. Originally the design was intended for the Roll On, Roll Off, ferries and commercial people carriers.
