Flame Retardent Silicone Products as used for the London Underground

Ronfell Group – Silicone Technology Division have pleasure in introducing our new Silfire high temperature fire / flame retardant rubber products in classification 1 and 2. We manufacture extrusion and rubber moulding materials in either Silicone rubber or EPDM, with applications at temperatures exceeding +300 Deg C and where a “Zero spread of flame” is required to specifications thus averting disasters.



Ronfell’s Section 12 protection System for London Underground, Tubelines and Metronet is a high specification system. It is manufactured from LUL compliant Ronsil 72 LCH1 flame retardant silicone rubber (Section 12 compliant) for sub-surface and surface station equipment.

Heat and Dust proof: Affords excellent protection from knocks, dents and scratches while equipment is being transported through the barriers during station refurbishment projects.

Easy Clean: With hot soapy water. Paint resistant.

Lightweight and Durable

Easy to Apply: Slips easily over the asset at any time.

Fully Compliant: Conforms to LUL requirements – Section 12 compliant.

Easy to Store: Folds up flat, minimal space requirement.

Minimises downtime: Speedy installation and removal maximises effective engineering production time.


Special 72 LCH1 is available in the form of mouldings, vacuum welded jointed sheets, profile extrusions and sheet.

It is particularly suited to use in engineering applications where public safety is a main concern. There is a wide range of standard colours available; although not all colours can be matched, Ronfell Group has a large amount of experience at being able to produce these materials in colours that are tailored to customer requirements.

Strong: Protect against Dust Contamination and extremes of Temperature: -10°C to +40°C with no Heat Build-up of asset.

Lightweight & Tough: Resilient Cloth Material.

Easy to Apply: Just slip easily over asset at any time.

Fully Compliant: Conform to LUL requirements.

Easy to Store: Folds up flat.

Reduced Disruption to Passenger Flow: Fewer Broken Gates needing to be left open thereby reducing losses from non-paying passengers. Keeps operational efficiency of the Station.

Reduced Penalties for Damaged Assets: Fewer Damaged Assets Leased from Prestige means less compensation to pay.



From a cost-efficient and widely used grade of rubber sheeting for various applications, technical grade rubber holds specific properties to meet your business needs, for food, beverages and pharmaceutical usage where purity of the rubber compound is essential to foam rubbers engineered to withhold there cellular structure, various applications including use with water, acids, and alkalis.


The Ronfell Group range of Cellular Silicone Elastomers is available as profile extrusions, jointed rings, sheeting, which can be self- adhesive backed, strip and punchings. They are particularly suited to use in high temperature seals and gaskets, where a soft, easily deformed rubber is required. There is a full range of standard colours available, and Silicone Engineering has the capability to colour match to customer requirements. Other specific sponge grades available include Flame retardant grades, SE515 & SE524 AFS1682, AMS3195, AMS3196 & BMS 1-60.
