Rubber properties

Rubber properties JRB Rubber compounds are designed for long life in marine environments. All fenders are made using high quality natural and/or synthetic rubber compounds, formulated for high performance and reliability.Rubber compounds include additives to resist the effects of ozone and ultra-violet light. The vulcanisation process (temperature, pressure and time) is strictly controlled to ensure a homogenous product with excellent physical properties and rubber to metal bond strengths.

Marine grade compounds
1. Natural and/or synthetic
2. Resists ozone and UV
3. Excellent bond strengths
4. Fully homogeneous
5. Fully recyclable

JRB moulded rubber fender compounds also comply to ASTM D 2000 callouts: 3BA 720 A14 B13 C12 EA14 F17 3BA 620 A14 B13 C12 EA14 F17
