REMARKS
The chemical resistance ratings are referred to the base resins used in our compounds and should be used for screening only. The resistance of our resins to chemical substances is significantly dependent upon the actual chemical exposure conditions such as time , temperature , concentration, etc. The importance of the various effects caused by the contact with chemical substances (swelling, absorption, loss of the mechanical properties and/or colour, etc) is instrumental in assigning the chemical resistance ratings. The negative ratings (C = poor resistance) may indicate a complete loss of mechanical properties or just a simple swelling. It is recommended that tests be always carried out on the selected product under actual application conditions, or conditions close to them. For any further information please contact LATI Technical Assistance.

Values shown are based on testing of injection moulded laboratory test specimens, conditioned according to the practice and represent data that fall within the standard range of properties for non-coloured material. As they may be subject to variations, these values do not represent a sufficient basis for any part design and are not intended for use in establishing values for specification purposes. Properties of moulded parts can be influenced by a wide range of factors including, but not limited to, colorants, part design, processing conditions, post-treatment and environmental conditions.
