BS – Double-Layered Molded Rubber. Hardness: 80 Shore A. (-20ºC to + 70ºC). Produced with molded double-layered vulcanized rubber tread over a grey cast iron wheel center. Ideal for external floor applications, offer a great shock and vibration absorption, high resistance to abrasion and longer service life due to their thicker rubber layer. Resistant to chemicals. They can be used at a speed of up to 20km/h when mounted with ball bearings.
PHP – Molded Polyurethane – High Performance. Hardness: 95 Shore A. (-40ºC to + 100ºC). Produced with a molded high performance polyurethane tread and grey cast iron wheel center. Ideal for applications on various surface and environment types. They offer excellent results with towed equipment. They withstand high loads, protect the floor, require less effort to handle, produce low noise level during handling, have an excellent resistance to tearing, impacts and abrasion, with a superior service life. They have an excellent resistance to weathering and chemicals such as greases, oils, salts and solvents. They can be used at a speed of up to 30km/h when mounted with ball bearings.
NHT – Fiberglass-reinforced Thermoplastic Compound. Hardness: 85 Shore D. (-20ºC to + 220ºC). Produced with a fiberglass-reinforced engineering thermoplastic compound. Indicated for utilization in high and low temperature applications. They are light and have an excellent mechanical resistance, roll very easily, requiring less effort in maneuvering and handling. Resistant to greases, oils, and some kinds of acids.
