Common industries: Glazing / architectural glass, construction, industrial equipment, glass handling, general manufacturing.
50 Durometer Industrial Grade Solid Neoprene is a commercial smooth-finish solid rubber sheeting based on an NBR/SBR/CR polymer blend, supplied powder free. At 50 Shore A, it provides a medium-soft profile suited for window setting blocks, isolation mounting pads, protective pads, adhesive applications, and vibration and shock damping in glass handling, glazing, and general industrial applications.
Natural aging resistance to alkalis and acids and good resistance to flame, abrasion, and flex cracking make it a versatile choice across industrial sealing and isolation use cases. Material is within Commercial Sheet Rubber Tolerances.
The grade exhibits limited resistance to ozone and weather, which should be considered for prolonged outdoor exposure. Heat aging performance at 212°F for 70 hours is characterized by hardness change of ±15 points max., tensile strength change of ±15% max., and elongation change of -50% max. Oil aging volume change is 120% max. after 70 hours @ 212°F per ASTM D471.
Compliant with ASTM D2000: 1BC510.
What differentiates 50 Durometer Industrial Grade Solid Neoprene from firmer grades in this series?
50 Durometer Industrial Grade Solid Neoprene is the softest standard grade in the industrial neoprene series, providing the highest compliance and conformability at 50 Shore A with a specific gravity of 1.24 gr/cc. It is the appropriate selection for isolation pad and window setting block applications where a softer, more compliant material is needed to absorb shock and accommodate surface variation without transmitting excessive load.
Why is compression set an important consideration for solid neoprene elastomers?
Compression set measures how well an elastomer recovers its original thickness after sustained compression. In isolation pads and setting blocks, high compression set means the material permanently flattens over time, losing its ability to absorb vibration and provide consistent load distribution. 50 Durometer Industrial Grade Solid Neoprene is rated at 80% max. compression set (22 hours @ 212°F per ASTM D395B), which is appropriate for industrial elastomer applications operating within the stated temperature range.
What is the temperature range for 50 Durometer Industrial Grade Solid Neoprene?
50 Durometer Industrial Grade Solid Neoprene is rated for service from -20°F to 190°F, as listed on the TDS.
Is 50 Durometer Industrial Grade Solid Neoprene suitable for specification-controlled environments?
Yes. This material meets ASTM D2000: 1BC510, as stated on the TDS. Note that ozone and weather resistance are listed as limited, which should be evaluated for prolonged outdoor or UV-exposed applications.
How should 50 Durometer Industrial Grade Solid Neoprene be specified?
Specify grade (50 Durometer Industrial Grade Solid Neoprene), thickness, compliance requirements (ASTM D2000: 1BC510), dimensional tolerances, and finished format.
