Synthetic polymers resins benefits

Plastic, polymer, resin, elastomer, and reinforced plastic (RP) are somewhat synonymous terms. The most popular term worldwide is plastics. Polymer denotes the basic material. Whereas plastic pertains to polymers or resins (as well as elastomers, RPs, etc.) containing additives, fillers, and/or reinforcements. An elastomer is a rubber-like material (natural or synthetic). Reinforced plastics (also called plastic composites) are plastics with reinforcing additives such as fibers and whiskers, added principally to increase the product s mechanical properties but also provides other benefits such as increased heat resistance and improved tolerance control. [Pg.5]

Relatively low molecular weight polymers such as polyacrylamides or polyvinylamines are widely used as synthetic dry strength additives. These offer both economic and quality benefits to the papermaker that could not be obtained through increases in refining or wet pressing. Additions of active resin as low as 0.2% can achieve increases in dry strength of up to 50%. Collateral benefits can include increases in retention, drainage, machine runnability, productivity and reduced raw material costs. [Pg.146]

The above discussion allows us to conclude that the bioassimilation of synthetic carbon-chain polymers has much in common with that of their natural analogues (notably natural rubber, resins and lignin). In all cases, nature uses abiotic oxidation chemistry together with biotic chemistry, very often together. The degradation products formed by oxo-biodegradation are of benefit to the agricultural environment as biomass and ultimately in the form of humus. [Pg.47]

PET is a thermoplastic polymer, which is produced on the most strength plastic widi high mechanical, diermal, and chemical resistance. PET is made from resin (polymer) synthetic, derived from oil, and its chemical composition is highly resistant to biodegradation. Plastics have significant volume md its separation brings many benefits, because the packaging its can be reused [16]. [Pg.231]
