Features Of Polypropylene PP sheets in roll For Thermoforming
البولي بروبيلين has the best electrical insulation and chemical resistance, the best mechanical properties and heat resistance in general thermoplastics, good fatigue resistance, the price of synthetic resin is one of the lowest varieties.The مادة البولي بروبيلين reinforced by glass fiber has high strength and similar properties to engineering plastics.The disadvantage of مادة البولي بروبيلين is that it has high brittleness at low temperature.Polypropylene processing performance is good, can use a variety of processing methods to produce products for different purposes.In isotactic polypropylene, the proportion of isotactic polymers is called isotactic index (or isotactic).In general, n-heptane reflux extraction is used to remove the residue after the random body and the polymer with low molecular weight, which is expressed by the mass fraction (%).This is only a rough measure, because some random isomers of high relative molecular mass and chains of isotopic, random, and interregular molecules of high relative molecular mass may not dissolve in n-heptane.Interregular polypropylene can exist as a whole molecule or as blocks of different lengths on isometric chains.The size of isotactic index affects a series of properties of polypropylene.The greater the isometric index, the higher the crystallinity of the polymer, the higher the melting temperature and the higher the heat resistance, the higher the elastic modulus, the higher the hardness, the higher the tensile strength, the higher the bending modulus and the lower the ductility.The relative molecular mass of polypropylene has an effect on its properties, but the effect law is slightly different from that of other materials.With the increase of relative molecular mass, melt viscosity increases, impact toughness increases, melting temperature, hardness, stiffness, yield strength and so on decrease, which is inconsistent with the general rule of other materials.This is due to the increase of relative molecular mass and the decrease of polypropylene crystallization, which leads to the deterioration of the properties of the material.

Specification Of Polypropylene PP sheets in roll For Thermoforming
According to the different structure, مادة البولي بروبيلين can be divided into three categories: isotactic, intermetric and random.At present, the main application is isotactic مادة البولي بروبيلين, the dosage can account for more than 90%.Atopic مادة البولي بروبيلين can be used as auxiliary agent, binder, modified material, etc., as the carrier of modified parent material, it has the characteristics of large viscosity, good fluidity, excellent coating effect, etc., due to the reasons such as output, price, use conditions, etc., at present, few manufacturers have used atopic مادة البولي بروبيلين as the carrier of modified parent material.M-gauge مادة البولي بروبيلين is a low crystalline polymer polymerized by metallocene catalyst and first developed in 1988. It is a high elastic thermoplastic material.Intermetric polypropylene has the advantages of transparency, toughness and flexibility, but its rigidity and hardness are only half of that of isometric مادة البولي بروبيلين.البولي بروبيلين can be vulcanized like ethylene propylene rubber, and the mechanical properties of the elastomer are better than that of ordinary rubber.Due to the high price, the current application of polypropylene is not wide, but has a promising future, is a new growth point of مادة البولي بروبيلين resin, is a new synthetic resin of modified materials.

Parameters Of أوراق pp pp pp في لفة من أجل التشكيل الحراري
البولي بروبيلين resin is a white, waxy, odorless, tasteless, non-toxic solid with a density of 0.89 ~ 0.92g/cm3. It is the lightest variety in plastic materials except poly4-methyl-1-pentene.It looks like polyethylene, but is lighter, more transparent and less permeable than polyethylene.Polypropylene flammable, after leaving the fire to continue to burn, the flame upper end is yellow, the lower end of the blue, there is a small amount of black smoke, after burning molten dripping, there is the smell of oil.Polypropylene has good comprehensive performance, abundant raw materials, simple production process and low price.
