Wells Plastics specialises in producing high performance, UV compatible, flame retardant masterbatches.
The products are formulated to process easily and have minimum impact on the physical aspect of the finished articles.
Many formulations find applications within the film and fibre marketplaces.
In addition to the above products Wells Plastics has developed grades for use in injection moulded and extruded ABS and polypropylene applications, offering UL94 V0 passes at low additions levels without significantly compromising impact strength and UV resistance properties.
Please contact Wells to discuss your specific requirements.
Application Examples:
Injection moulding, profile extrusion, fibre and film.

As many plastics are inherently flammable, measures must be taken to increase their safety in applications where there is the risk of fire. Often the most cost effective method of doing this is to add a flame retardant additive during processing.
Careful choice of the flame retardant for a particular polymer and application is important. Additives must be chosen to function properly in the polymer they need to protect. Other properties of the flame retardant must also be considered: the additive should be compatible with the polymer, it should not adversely affect physical properties and ideally be effective at low addition rates. Additionally, in certain applications, it is desirable that the additive is colourless and does not affect UV stability.
In addition to these properties the additive should have low toxicity, low smoke emission and minimise toxic breakdown products in a fire situation.
Wells Plastics has been at the forefront of flame retardant masterbatch manufacture for many years. As well as conventional products such as polyhalogenated organics with synergists such as antimony trioxide, Wells has developed a range of inorganic and organic non-halogenated grades.
Wells’ experience in this area enables us to work with our clients to establish the optimum grades for their applications.
Wells Plastics has developed a range of products based upon a polyhalogenated phosphate flame retardant additive package. These products are particularly suited for use in film and fibre applications as they require no additional synergists such as antimony trioxide. These novel formulations offer excellent flame retardant properties at relatively low addition levels. They show excellent UV/light stability together with high heat resistance, having an upper processing temperature of 270oC. In addition they have low toxicity and low environmental impact, the additive passing the stringent German Dioxin Ordinance.
