Properties & Application
The chemical resistance of tyres depends on the temperature and period of contact with the medium.
The following chemical resistance data refers to working analysis of materials produced and also to test results and experiences from our customers.
Colouring of tyres
Black rubber does not normally change colour.
After a period of time with static load flats may occur to the tyre – so called compression set.
Conditions of application
The quality of the tyre as well as the wheel dia-meter are declined by the nature of the road surface.
Conducthane® is an advanced development based on Vulkollan® (NDI) which is classified as conductive following to DIN/EN12527-33.
DynaRoll® is an advanced special elastomer from Wicke for high demands based on the raw material Desmodur® 15 from Bayer AG® Leverkusen.
Elasthane® is a high resistant Polyurethane (MDI) with good solidity and abrasion values.
Tyres are non-conductive products with an electric resistance of 109 – 1012 ohm.
FilaTron® is a Wicke inhouse advanced development of the known Vulkollan® tyre (NDI) based on the raw material Desmodur® 15 from Bayer AG® Leverkusen.
The friction value µ of the tyre material is important for powered or braked wheels.
Greythane® 75 Shore A is a high-class grey Polyurethane (MDI) with elastic rubber characteristics and excellent traction values.
Load capacity of wheel/of tyre
Midthane 85® Shore A is a high-class olive-green Polyurethane (MDI) with elastic rubber chracteristics and the hardness is optimized for ergonomic and low-noise movement.
Pressure on the ground
The contact surface to the floor depends on the pressure on the ground.
Redthane® 75 Shore A is a high-class red Polyurethane (MDI) with elastic rubber characteristics and excellent traction values.
The extent of the deformation of the tyre is called resilience and characterizing the driving comfort.
Wicke RockThane® 96 Shore A is a high wear resistant Polyurethane (MDI) with good solidity and abrasion values.
On critical floors a diffusion of the tyre additives may cause an irreversible discolouration which is called staining.
Starting and rolling resistance
The starting and rolling resistance are decisive for the power required for the movement of the vehicle.
Staticthane® is an advanced development based on Wicke Topthane®.
Tyres should be stored dry, cool and secured against direct sunlight.
SuperTrac® is a Wicke in-house advanced development of the known Vulkollan® tyre (NDI) based on the raw material Desmodur® 15 from Bayer AG® Leverkusen.
All index-datas are based on a temperature of +30°C.
Wicke Topthane® 92 Shore A is a high wear resistant Polyurethane (MDI) with good solidity and abrasion values.
Type of tyre
The choice of tyre with the correct wheel or castor is crucially important.
Vulkollan® is the toughest highest quality Polyurethane based on Desmodur® 15 from Bayer® Leverkusen.
TOPTHANE®, Polyamid as well as solid rubber tyres offer excellent resistance to climatic conditions (ozone) and most atmospheric pollution by containing admixtures against superannuation.
Wicke ELASTIC®-black is a high resistant rubber tyre with a hardness of 73 Shore A.
Wicke ELASTIC®-grey is a high resistant rubber tyre with a hardness of 73 Shore A.
