Polypropylene waxes

Other additives. Amorphous polypropylene, waxes and asphalt can be added to decrease the cost of BR formulations. On the other hand, PIB can be blended with NR, styrene-butadiene rubber, EVA and low molecular weight polyethylene to impart specific properties. 

Specialty waxes include polar waxes for more polar adhesive systems. Examples would be castor wax (triglyceride of 12-hydroxy stearic acid) or Paracin wax N- 2 hydroxy ethyl)-12-hydroxy stearamide) which are used in polyester, polyamide, or with high VA EVA copolymer-based systems. Other common polar waxes are maleated polyethylenes, which are used to improve the specific adhesion of polyethylene-based adhesives, and low molecular weight ethylene copolymers with vinyl acetate or acrylic acid, which are used to improve low temperature adhesion. High melting point isotactic polypropylene wax (7 155°C) and highly refined paraffin wax (7,n 83°C) are used where maximum heat resistance is critical. Needless to say, these specialty waxes also command a premium price, ranging from 2 to 5 times that of conventional paraffin wax. 

Polar polypropylene waxes are produced by grafting of PP with maleic anhydride. 

With alcohols, chlorine produces alkyl hypochlorites, which explode on exposure to sunlight or heat. Reaction of chlorine with formaldehyde, acetaldehyde, or diethyl ether is violent. Liquid chlorine reacts explosively with carbon disulfide, glycerol, dialkyl phthalates, polypropylene, wax, rubber, and linseed oil. 

So that coatings based on UP resins can be applied on vertical surfaces, they are made thixotropic. This is done either by using thixotropic resins or by combining standard resins with, for example, highly disperse silicic acid, bentonite and/or hydrated caster oil derivatives. To produce matt coatings, waxes (polyethylene and polypropylene waxes) and/or silicic acid are added in amounts up to 10%.

Chun and Woodhams [39] reported significant increases in tensile strength but little effect on impact strength by using a maleated polypropylene wax with mica in a PP homopolymer. Lower levels of additive were needed than in the work with AA-g-PP described above. The authors also found a synergistic effect with some silane treatments. 

The munber of carbon atoms in the lubricant molecule s carbon chains can range from a minimum of about 14 in some fatty acids through 20 to 50 carbons in paraffin waxes up to several hundred in polyethylene and polypropylene wax. Generally, the smaller the number of carbon atoms, the more internal (rather than external) is the lubricant character, and the higher molecular weight substances are likely to behave as externals, although polarity (which can be modified by oxidation) can affect the solubihty of the wax in a polymer, as can molecular weight. 

Clariant offers a maleated PP imder the Hostamont name. Around the end of 2003 Clariant also introduced a maleated polypropylene wax called Licomont AR 504 as a coupling agent and compatibihser, also for wood and natural fibre composites. The viscosity was deliberately low to facilitate fibre impregnation. Benefits claimed were improvements in the toughness and elasticity of the products. 

Although desirable, organic pigments present problems because they are more resistant to breakdown and dispersion, with limited heat stability and less interaction with the matrix. No single dispersant has been able to correct this. Polyethylene and polypropylene waxes are used as carriers for pigments, but it has been difficult to ensure complete avoidance of agglomerates.
