    • Shrinkage according to Literature: 0,45% to 0,8% (depending on the part geometry and the process)
    • Setting may be different depending on the part design and machine type of recommend values.

    Test Values
    The stated values were - if not otherwise stated - taken on standardized test specimen at room ambient temperature. The specifications have to be regarded as guidance values, but not as binding minimum values. Please note that the properties can be considerably influenced by mould design, processing parameters and colouring.

    Processing instructions
    When processing on the basis of the recommended processing parameters, small quantities of dissociation products can emit. According to the safety data sheet, the workplace exposure limit has to be kept by means of adequate exhaustion and ventilation, in order not to affect the machine operators’ health and well-being. The compulsory processing temperatures must not be considerably exceeded, in order to avoid a stronger partial decomposition of the polymers and dissociation of volatile decomposition products.
