SP – Extra Soft Thermoplastic Rubber. Hardness: 65 Shore A. (-10ºC to + 50ºC). Injected recyclable thermoplastic extra soft rubber tread and polypropylene copolymer wheel center. Its advantages are the extremely low noise level and vibration reduction. Indicated for light load handling, they offer an excellent floor protection and regular resistance to impacts and chemicals. Nominal working speed is up to 4km/h.
TM – Termic. Hardness: 90 Shore D. (0ºC to + 200ºC). Manufactured in phenolic resin (bakelite), molded by heat and pressure. Indicated for utilization in high temperature environment applications. They have good mechanical properties, resistant to deformation under static loads and roll easily. They are resistant to most chemicals.
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.
