Understanding Rubber Hardness
Shore A Hardness Scale Explained:
| 20-30 Shore A: | Very soft (rubber band flexibility) |

| 50-60 Shore A: | Medium – general industrial applications |
| 70 Shore A: | Firm – load-bearing, wheels, solid tyres |
| 80+ Shore A: | Hard – minimal flexibility, maximum load capacity |

Frequently Asked Questions
What is natural rubber sheet best used for?
Natural rubber (NR) excels where abrasion resistance, high elasticity, and tear strength are critical. Top applications include conveyor belt skirting, mining chute liners, industrial flooring, anti-vibration mounts, and impact-absorbing pads. Its 80%+ rebound resilience makes it ideal for shock absorption. Avoid using NR with oils, fuels, or in prolonged UV exposure.
What is the difference between natural rubber and synthetic rubber?
Natural rubber (from Hevea brasiliensis latex) offers superior tensile strength (15-25 MPa), tear resistance, and abrasion resistance compared to most synthetics. However, synthetic rubbers like nitrile (NBR) offer better oil resistance, EPDM offers better weather resistance, and silicone offers higher temperature tolerance. Choose NR when mechanical properties matter most; choose synthetics for chemical/environmental resistance.
Can natural rubber be used outdoors?
Natural rubber has poor ozone and UV resistance, causing surface cracking (known as 'ozone cracking' or 'weather checking') within 6-12 months of outdoor exposure. For outdoor applications, use EPDM or neoprene rubber instead. NR is best suited for indoor industrial environments, covered loading bays, and applications where it's protected from direct sunlight.
Is natural rubber oil resistant?
No. Natural rubber swells and degrades when exposed to petroleum oils, fuels, and most solvents. For oil-contact applications, use nitrile rubber (NBR) which offers excellent oil resistance. Natural rubber is suitable for water, air, dilute acids, and general-purpose applications where oil contact is not expected.
What does Shore A hardness mean for rubber?
Shore A hardness measures rubber flexibility on a 0-100 scale. Our 40 Shore A natural rubber is soft and flexible (like a pencil eraser), ideal for seals and gaskets. 60 Shore A is medium hardness suitable for general industrial use. 70+ Shore A is firm, used for load-bearing applications. For anti-vibration mounts, 40-50 Shore A is typically specified.
How do I cut natural rubber sheet?
For thin sheets (3-6mm): use a sharp Stanley knife or rotary cutter against a straight edge. For thicker sheets (10mm+): use a jigsaw with a fine-toothed blade, or a bandsaw. Always cut on a stable surface. For curved cuts, a hole saw or leather punch works well. We can also supply pre-cut pieces to your specifications – contact us for a quote.
