Starting and rolling resistance


The starting and rolling resistance are decisive for the power required for the movement of the vehicle.


Application matrix


Properties & Application


Type of tyre


The choice of tyre with the correct wheel or castor is crucially important.


Conditions of application


The quality of the tyre as well as the wheel diameter are defined by the nature of the road surface.


Weather


TOPTHANE®, Polyamid as well as solid rubber tyres offer excellent resistance to climatic conditions (ozone) and most atmospheric pollution by containing admixtures against superannuation.


Pressure on the ground


The contact surface to the floor depends on the pressure on the ground.


Chemical resistance


The chemical resistance of tyres depends on the temperature and period of contact with the medium.


Chemical resistances


The following chemical resistance data refers to working analysis of materials produced and also to test results and experiences from our customers.


Conducthane


Conducthane® is an advanced development based on Vulkollan® (NDI) which is classified as conductive following to DIN/EN12527-33.


Compression


After a period of time with static load flats may occur to the tyre – so called "compression set".


DynaRoll G-II


DynaRoll® is an advanced special elastomer from Wicke for high demands based on the raw material Desmodur® 15 from Covestro Group®.


Resilience


The extent of the deformation of the tyre is called resilience and characterizing the driving comfort.


Elasthane


Elasthane® is a high resistant Polyurethane (MDI) with good solidity and abrasion values.


Electric characteristics


Tyres are non-conductive products with an electric resistance of 109 – 1012 ohm.


FilaTron


FilaTron® is a Wicke inhouse advanced development of the known Vulkollan® tyre (NDI) based on the raw material Desmodur® 15 from Covestro Group®.


Greythane


Greythane® 75 Shore A is a high-class grey Polyurethane (MDI) with elastic rubber characteristics and excellent traction values.


Staining


On critical floors a diffusion of the tyre additives may cause an irreversible discolouration which is called staining.


Bearing


Tyres should be stored dry, cool and secured against direct sunlight.


Midthane


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.


Redthane


Redthane® 75 Shore A is a high-class red Polyurethane (MDI) with elastic rubber characteristics and excellent traction values. Improved combinations of chemical and physical features offer best results for applications in fields without extreme demands on loads, distances and speeds.


Friction values


The friction value µ of the tyre material is important for powered or braked wheels.


Load capacity of wheel/of tyre





Colouring of tyres


Black rubber does not normally change colour.


Rockthane


Wicke Rockthane® 96 Shore A is a high wear resistant Polyurethane (MDI) with good solidity and abrasion values.


Staticthane


Staticthane® is an advanced development based on Wicke Topthane®.


SuperTrac


SuperTrac® is a Wicke in-house advanced development of the known Vulkollan® tyre (NDI) based on the raw material Desmodur® 15 from Covestro Group®.


Thermical capacity


All index-datas are based on a temperature of +30°C.


Topthane


Wicke Topthane® 92 Shore A is a high wear resistant Polyurethane (MDI) with good solidity and abrasion values.


Vulkollan


Vulkollan® is the toughest highest quality Polyurethane based on Desmodur® 15 from Covestro Group®.
