MAXFLEX FR Black Rubber Insulation Sheet

MaxFlex FR

MAXFLEX FR Black Rubber Sheet Insulation is ideal for cold applications with operating temperatures from -57 to 125°C, offering superior low thermal conductivity compared to other insulation types.

 

ค่าการนำความร้อน Thermal Conductivity

Thermal conductivity indicates how much heat a material can transmit. A higher value means the material can transfer heat more quickly and efficiently. Therefore, good thermal insulation should have a low thermal conductivity value, ideally close to 0.

MaxFlex FR Black Rubber Sheet has low thermal conductivity at 0.031 W/m.K at 0°C, making it excellent for cold applications with minimal energy loss.

 

การต้านทานรังสีUV

MaxFlex FR’s EPDM rubber composition provides superior UV resistance. Testing at Department of Science Service with UVB-313 at 60°C for 8 hours showed no changes.

This ensures that when installed and exposed to sunlight, it can withstand without cracking. However, if MaxFlex FR black rubber insulation is installed outdoors and exposed to sunlight and weather conditions, it should be jacketed to extend the material’s lifespan due to weather and biological factors.

การดูดซับน้ำ Water Absorption

The water absorption property of materials in insulation applications should be low. In black rubber insulation applications that encounter low temperatures, condensation can easily occur, which can cause pipe corrosion or damage to other materials.

Therefore, black rubber insulation or other types of insulation should not absorb water. The water absorption of MaxFlex FR black rubber insulation is less than 0.05% by volume, which is extremely low – practically non-absorbent.

 

ประสิทธิภาพเกี่ยวกับเพลิง Fire Performance

Building systems have strict requirements for materials, especially regarding flammability. Black rubber insulation is used in water pipe systems or air conditioning systems, which run throughout the building. If the material attached to the pipes catches fire, it could spread quickly throughout the building.

Insulation in pipe systems or air conditioning systems must therefore be fire-resistant. We have tested the fire resistance of MaxFlex FR black rubber insulation according to many standards including BS 476 Part 7, UL 94, ASTM D635, and it has been confirmed as a non-flammable material. When ignited, the flame will self-extinguish.
