Too many or too few stabilizers

Too many or too few stabilizers Stabilizer according to the different types of plastic profiles are different, but the total point, the excessive use of materials will delay the plasticizing time so that when the material export mold is also less plastic, the formula system between the molecules are not completely dissolved Combined, the intermolecular structure is not strong.sliding door frame laminate profiles with filmWhen the dosage is too small, it will cause the degradation or decomposition of relatively low molecular substances in the formulation system (which can also be said to be plasticized) , and the stability of the intermolecular structure of each component is damaged. So the amount of stabilizer will also affect the impact of plastic profiles impact strength, too much or too little will cause the reduction of the profile of plastic profiles caused by brittle phenomenon. Excessive amount of external lubricant The low compatibility between the external lubricant and the resin can promote the sliding between the resin particles, thereby reducing the amount of frictional heat and delaying the melting process. This effect of the lubricant is greatest at the early stage of the process. Lubricants are divided into pre-lubrication and post-lubrication, lubricating over the material under a variety of conditions are poor appearance,cheap house windows upvc profile for sale if the amount of lubricant is not correct, may cause flow marks, low yield, turbidity, poor impact, rough surface , Adhesion, poor plasticity. Especially when the amount is too much, it will cause poor density of plastic profiles, poor plastic, which led to poor impact performance, causing plastic profiles brittle.
