- BASF (Glissopal® and Oppanol®) is a leading manufacturer of polyisobutene.
APPLICATIONS
The most popular commodity thermoplastic is polyethylene. LLDPE, LDPE, and HDPE are the three most valuable grades in terms of volume. Construction, consumer products, electronics, electricity, and transportation are only a few of the many possible fields of use. Containers, buckets, pipes, toys, covers, lids, plastic bags, stretch wraps, plastic wraps, sheets, films, bottles, and extrusion-coated paper cartons are just some examples of the many consumer goods that make use of PE in their production.
Isotactic polypropylene (i-PP) is the second most common polyolefin. It has similar applications to polyethylene (PE). In many applications, i-PP is competitive with HDPE. The melting point, crack resistance, heat deflection temperature, and, in many situations, tensile strength are all higher than those of HDPE. The stress crack resistance of i-PP is exceptional. When compared to HDPE, it has lower resistance to heat, light, ultraviolet light, and oxidation. Unless further resistance to thermooxidative deterioration is necessary, i-PP is typically the superior choice for more demanding applications.
Production of polyisobutene (PIB) is significantly lower. Materials with low molecular weights are sticky; those in the middle range are oily; and those with high molecular weights are elastic and rubbery. You can find PIB in a wide variety of products, including synthetic rubber (butyl rubber), adhesives, sealants, chewing gum, roofing membranes, lubricants, cable filler, and more.
PB-1, or polybutene-1, is another low-volume polyolefin. Since the two molecules are so close in structure, it can be employed to enhance polypropylene’s mechanical qualities when heated. Pressure pipes for both hot and cold (drinking) water, as well as consumer and medical packaging, are two more prominent uses. Adhesives, sealants, paper laminates, and tapes all benefit from the increased tack and peel strength provided by low-molecular-weight grades. It can be used in conjunction with a wide variety of nonpolar resins without much trouble.
