Surface property

PTMB slip masterbatches are used to enhance the smoothness of films by reducing the tackiness to sliding over itself or parts of converting equipment with reduction of film coefficient of friction. It functions by migrating to the surface and forming a lubrication layer on it with no adverse effect on the printing and sealing properties.

PTMB anti-slip masterbatches are based on an organic and inorganic chemical with non-migrating property which gives no adverse effect in machine or final products. It is recommended to give a sandpaper like surface effect for the modification of thick films (>80 to 100 microns). It has property to give rough surface without affecting the machine screw and barrel as there is no abrasive material used.

PTMB have developed a range of anti-blocking additives masterbatches which modify the surface characteristic by creating a micro-rough surfaces or smoother surface, thus reducing the coefficient of friction. This helps to prevent self-adhesion of plastic film or sheet, making it easier to handle.

PTMB Antistatic Masterbatches are used in order to reduce static charge buildup and lowering the surface resistivity of plastics products during processing and uses. It modifies the resistivity levels of plastics to values below 1010 ohms.sq. which allows any charge decay to the earth.

Anti-fog additive masterbatches are added to polyolefin films to reduce their surface tension thereby preventing the formation of water droplets on the film surface for maintaining the film transparency which is needed in hot or cold food, fruits or vegetable packaging.

PTMB anti-fog additives masterbatches eliminates this problem by lowering the surface tension of water droplets causing this hence maintaining the clarity of the film.

PTMB Anti-tack additives are commonly employed in the plastics industry in order to prevent adhesion of plastic objects to themselves, to each other and/ or to other objects.

PTMB anti-scratch additives improve the scratch and mar resistance in PP., TPO and other polymers. It can impart scratch and mar resistance up to 10-15 newtons with 5-finger and the cross Erichsen tests which is used by most of automotive producers.

Matte Effect Masterbatches from PTMB are added to polymers to modify surface properties to reduce gloss and develop a matte or paper effect in PE, PP, PET film and sheet product application.
