China Flame Retardant Rubber Seals Manufacturer, Fire Protection EPDM Self-gripping Gaskets Supplier, Rubber Extrusions Factory
We are a leading China manufacturer of flame retardant rubber seals, EPDM fire protection gaskets, extruded profiles, UL 94 V-0 rated EPDM rubber extrusions, extruded EPDM rubber seals, fire resistant rubber profiles, fire protection sealing profiles, gaksets, flame retardant rubber seals, fire retardant edge trim seals, fireproof rubber seals, sponge rubber seals, flame retardant gaskets, fire retardant gasket, FMVSS 302, window extrusions, door seals. Hebei Shida Seal Group design and manufactures UL Flame Retardant EPDM rubber compounds for a variety of applications. These compounds are available as: spliced and fabricated rubber gaskets, long length rubber extrusions, profiles, and precision extruded and cut seals.
UL 94 V-0 Listed EPDM Rubber Compound:
We offer Flame Retardant EPDM rubber compound certified to UL 94 V-0. The UL 94 V-0 testing covers the flammability characteristics of rubber materials. UL defines the Vertical Burning rate (V0, V1, V2) as the calculation of the vertical burn rate in millimeters per minute. By passing the most difficult V0 rating, our Flame Retardant EPDM rubber compound also exceeds the requirements for V1, V2, and HB and therefore can be considered in such applications.

UL 94 V-0, V-1, & V-2 Requirements
|
Criteria Conditions |
V-0 | V-1 | V-2 |
| Afterflame – Persistence of flaming of a material, after the ignition source has been removed Afterflame Test – Time for each specification | < or = 10s | < or = 30s | < or = 30s |
| Total Afterflame Time – The length of time for which a material continues to flame, under specified conditions, after the ignition source has been removed. Total Afterflame Time Test – For 5 samples | < or = 50s | < or = 250s | < or = 250s |
| Afterglow Time – The length of time for which a material continues to glow under specified test conditions, after the ignition source has been removed and/or cessation of flaming. Afterflame Plus Afterglow Time Test – For each individual specification after second flame application | < or = 30s | < or = 60s | < or = 60s |
| Afterglow – Persistence of glowing of a material, after cessation of flaming or, if no flaming occurs, after the removal of the ignition source. Test – Afterflame or Afterglow of any specification | No | No | No |
| Cotton indicator ignited by flaming particles or drops | No | No | Yes |
UL 94 HB Requirements
| UL 94 HB (Horizontal Burning) is the calculation of the linear burn rate in millimeters per minute.Test – Not to have a burning rate exceeding 75mm per minute over a 75mm for specifications having a thickness less than 3.0mm (0.188”), or cease to burn before the 100mm reference mark. |
Hebei Shida Seal Group also manufactures fire retardant rubber extrusions, seals, profiles, flame retardant EPDM rubber profiles, UL 94 V-0 rated EPDM rubber extrusions, extruded EPDM rubber seals, fire resistant rubber profiles, fire protection sealing profiles, gaksets, flame retardant rubber seals, fire retardant edge trim seals, fireproof rubber seals, sponge rubber seals, flame retardant sealing gaskets, fire retardant gasket, gaskets made of fire protection compound to Chinese national standard: GB 8410-2006 Flammability of automotive interior materials, which is similar to Federal Motor Vehicles Safety Standards FMVSS 302 – Flammability of materials used in the occupant compartments of motor vehicles. FMVSS 302 from the U.S. National Highway Safety Traffic Administration (NHTSA) specifies burn resistance requirements for materials used in occupant compartments. Technically equivalent to ISO 3795 and ASTM D5132-04, FMVSS 302 applies to buses, trucks, passenger cars, and multi-purpose passenger vehicles.
Fire Retardant Rubber Seal
GB 8410-2006 Scope
This Standard specifies the technical requirements and test methods for the horizontal flammability of automotive interior materials. This Standard applies to the assessment of automotive interior materials.
GB 8410-2006 Technical requirements：
The flammability of interior materials must meet the following technical requirement:
The burning rate is not greater than 100 mm/min.
The burning rate of our EPDM rubber seal is far less than 100mm/min.
