General Description
Technical Specifications for Phenolic products – Our Phenolic panels are a composite sheet product consisting mainly of cured phenolic resin and glassfibre. It is one of the most effective cosmetic FIRE RESISTANT sheet materials available, producing relatively minute quantities of smoke and toxic fumes when exposed to fire – whist still retaining excellent physical properties at high temperatures. It is easily cleaned, has a graffiti resistant surface, is shatterproof, has similar if not better physical attributes to other composites.

PHENCLAD is a composite sheet product consisting mainly of cured phenolic resin and glass fibre. PHENCLAD is one of the most effective cosmetic fire resistant sheet materials available producing comparatively minute quantities of smoke and toxic fumes when exposed to fire – well within the most stringent limits of any international fire standard – while still retaining excellent physical properties at high temperatures. PHENCLAD is manufactured to the highest quality standards using a computer controlled continuous process. PHENCLAD is ideal for cladding, lining, partitioning, panelling and many other applications. It is available in a wide range of colours and in several surface finishes and may also be bonded to other materials to provide for a wider range of applications.

Phenol Formaldehyde (Phenolic) resins have been in commercial use for just under 100 years. Recent advances in resin/catalyst technology and continuing improvements in glass fibre production techniques combined with unique processing methods have made the manufacture of PHENCLAD possible. The product has undergone relevant tests by an internationally recognised Fire Research Centre. Copies of the results can be made available on request by interested parties. Details of the tests are as follows:

Cutting and Handling
PHENCLAD is relatively easy to handle and install using a variety of complementary fixing systems. It can be drilled, sawn, cut and machined using standard tools and equipment.
Size & Thickness
PHENCLAD can be produced to a wide range of dimension with thickness from 3mm to 6mm, width up to 1500mm and virtually any reasonable length. Generally, stock sheet sizes are 1200 x 2400 mm. Non-standards can be made available on request.
Health and Safety
As with other sheet products, careful handling and lifting, using gloves, will minimise accidents. Good workshop practices should be in place when machining, i.e. Proper ventilation, extraction, dust masks, visor/glasses and gloves. In food processing areas, damaged or scuffed sheets exposing fibres below the surface coating should be replaced or sealed using materials as advised by the manufacturer.
Environment
PHENCLAD will not contribute significant amounts of smoke or toxic fumes into the atmosphere as a result of fire. It will also replace many materials which are in dwindling supply (e.g. hardwoods) and others which consume high amounts of energy during manufacture (e.g. aluminium, steel). On completion of its useful life – for whatever reason – PHENCLAD can be crushed and recycled as a filler for a variety of purposes.
Quality Statement
Quality controls are in place in the procurement and storage of materials, throughout the process operation and at packing and despatch. Staff are employed on work of which they have full understanding and which falls within their known capabilities. Materials are purchased on the ‘most suitable for the job’ principle with non-conforming materials stored remotely and returned to the supplier. Intermittent quality audits are carried out by the management who are fully committed to the installation of quality control systems that comply with recognised international standards.
Due to the wide variety of products and variations available in the Fybaplate range, the following technical specifications should be considered as a guide only. Please contact us directly for more accurate product qualities and performance ratings.
Smyth Composites Limited operate as a “Toll Manufacturer” and therefore advise that Customers MUST satisfy themselves that the products they order are fit for the intended purpose.
