Embossing improved with medium wave

Carbon infrared (CIR) emitters from Heraeus Noblelight are helping Polyflor in Manchester to improve the quality of its flooring products and boosting dimensional stability during the embossing of its range of heavy duty homogenous floor coverings.

Polyflor's embossing process had previously used short wave infrared units to soften the 2m wide PVC web before being embossed with decorative patterns.However,Heraeus says short wave proved colourselective and geometric integrity was sometimes affected during heating.

Heraeus showed that medium wave infrared would ensure efficient drying results during embossing and a carbon infrared system was subsequently installed.

Heraeus specialises in the production and application of energy sources covering the electro-magnetic spectrum from ultraviolet to infrared.
