Polypropylene impact copolymers

Chem. Descrip. Anhydride-modified polypropylene impact copolymer CAS 900 074)... [Pg.370]

Hyperfom HPN 210 M is a new nucleating agent for injection molded high-density polyethylene apphcations. It improves mechanical performance to the levels approaching those of polypropylene impact copolymers. It increases stiffness by up to 50%, heat distortion temperature by 10-40°C, and productivity. It has ability to create lamellar crystal orientation of PE in the polymer flow direction reducing shrinkage. ... [Pg.111]

A hot melt adhesive composition made from polypropylene copolymer or polypropylene impact copolymer, a polyolefin elastomer, a low density polyethylene, a tackilying resin, a plasticizer, and a nucleating agent The 0.2 to 1 wt% of nucleating agent is... [Pg.183]

Some of the useful information derived from DSC heating scans includes the melting temperature, which is taken as the maximum of the endothermic peak, and the heat of fusion, determined by integrating the area under the endothermic peak. The melting temperature of PP homopolymer is about 160°C, whereas that of usual PP random copolymers is about 145°C. Polypropylene impact copolymers exhibit the same melting temperatures as homopolymers, the rubber constituent not affecting the melting temperature. Impact copolymers do, however, have lower heats of fusion than homopolymers because the heat of fusion is related to the proportion of crystalline polymer present. The rubber portion is essentially noncrystalline and therefore does not melt. [Pg.22]

Substrates Polypropylene impact copolymer nominal MFl 35 dg/min and high-density polyethylene nominal MFl 18 dg/min. were used. [Pg.2346]

Polypropylene is extensively used in injection molding because of the wide range of physical properties and melt flow rates available. The principal markets served include transportation (primarily automotive), appliances, consumer products, rigid packaging, and medical products. Polypropylene use has increased in the automotive industry because of the wide availability of high melt flow rate impact copolymers for use in large thin parts, such as interior trim. [Pg.1147]

Fig. 44. The SFM amplitude (a) and force modulation (b) maps of a cryogenic faced impact copolymer (ICP) composed of a polypropylene (PP) matrix with high ethylene (60 wt. %) ethylene-propylene copolymer (EP). Crystalline polyethylene (PE) phases are seen in the EP domains, which are surrounded by the PP matrix. Modulus contrast in the force modulation (drive amplitude 100 mV) image associated with the three polymers the stiff PP matrix is dark, the soft EP domains are light. The crystalline PE regions have modulus between the PP and the EP,thus an intermediate shade of grey is observed for the PE domains [128]... Fig. 44.
