Best on test: virgin versus recycled rubber fenders

Compound test results of Trelleborg fender versus low cost fenders conducted in 3rd party laboratory:Sample: Collected from fenders delivered to a Trelleborg client (ie. shared client).Tests conducted: Physical and chemical analysis, using sophisticated analytical methods.

Property Test method Trelleborg fender Low cost fender Comments
Specific gravity BS903 A1 1.15 1.29 Higher value indicated usage of recycled and high density cheap filler
Tensile strength (Mpa) BS 903 A2 15.4 9.3 Very low compared to Trelleborg fender
Elongation @ break (%) BS 903 A2 364 278 Very low compared to Trelleborg fender
Polymer % ASTM D6370 46 42.6 Higher is better for recovery and properties
Carbon Black % ASTM D6370 33.5 26.9 Higher is better for boosting physical properties
Ash % ASTM D297 3.7 21.5 More than 5% is detrimental to the physical properties, ie. less resilience and elasticity leading to reduced longevity
Caco3 % ASTM D4004 0.49 15.54 More than 2% is used to reduce the cost
