Low density polyethylene (LDPE) resins are used for a large number of high performance and general purpose applications. There are a great variety of specific grades for different transformation techniques.
Extrusion: for the production of blown film sheets with a wide range of thicknesses, for the manufacture of blown hollow bodies, cables and coatings for other materials, such as paper and cardboard.
Injection: Injection moulding along with extrusion ranks as one of the prime processes for producing plastics articles.
Rotomoulding: Rotational moulding, also known as rotomoulding, is a plastics moulding technology which is ideal for making hollow articles.
Butene C4 is available in various densities: from high (up to 0.941 g/cm3) to very low (0.905 g/cm3). LLDPE is used for film extrusion, Blow Moulding, Rotomoulding and Injection Moulding for packaging food, frozen food, radiation heating pipes and cosmetic and pharmaceutical applications.
Octene C8 is available in various densities: from high (up to 0.941 g/cm3) to very low (0.905 g/cm3). LLDPE is used for film extrusion, blow moulding, rotomoulding and injection moulding for packaging food, frozen food, radiation heating pipes and cosmetic and pharmaceutical applications.

MDPE is a thermoplastic within the polyethylene family with a density of 0.926-0.940 g/cm3, which is less dense than the more common HDPE.
A versatile thermoplastic polymer with a great cost/performance ratio. Its general hardness, flexibility and impact resistance at low temperatures make it ideal for consumer and industrial products. By complying with FDA regulations it is appropriate for food and medical applications.
HDPE resins are the choice for many applications due to their resistance to cracking, rigidity and ability to withstand high temperatures and deformation. They provide a great range of properties for almost any blow moulding process for hollow bodies.
HDPE resins are used in blown film applications where rigidity and low thickness are very important. The composition of HDPE offers optimum performance features for blown film processes.
Notable mainly for its strength, low cost and impact resistance
EVA is an elastomer used to produce materials that look “rubbery” due to their softness and flexibility. The vinyl acetate content determines the degree of elasticity; it also has good transparency and gloss and resistance at low temperature to stress cracking and UV radiation. EVA has a slight characteristic odour of vinegar (acetic acid) and competes with rubber products, as well as with certain polymers in many electrical applications.
Polypropylene is an economical material that offers a combination of excellent physical, mechanical, thermal and electrical properties not found in any other thermoplastic. Compared with low or high density polyethylene, it has lower impact resistance, but a higher temperature resistance and higher tensile strength.
Polypropylene homopolymer (PPH) is the most used. It has a high strength/weight ratio and is more rigid than the copolymer. This, combined with good chemical resistance and weldability, means it is used in many corrosion resistant structures
Polypropylene copolymer (PPC) is a bit softer, but has better impact resistance, is stronger and more durable than polypropylene homopolymer (PPH). It tends to have a better resistance to stress cracking and a lower strength at temperature than the homopolymer, with other slight reductions in the performance of other properties
Random PPC, unlike PPC, has the comonomer units arranged in irregular or random patterns along the polypropylene molecule. They are generally selected for applications where a more malleable and more transparent product is desired, although with less impact resistance than PPC
Polypropylene is the second-most widely produced commodity plastic (after polyethylene) and it is often used in packaging and labeling. Polypropylene has similar properties as Polyethylene but its slightly harder and more heat resistant. These compounds are thermoplastic resins and are produced using a mixture of one or more base polyolefins with various components as impact modifiers, fillers and strengtheners (e.g. mineral fillers and glass fibre), pigments and additives.
Nylon-6 is tough, lightweight, abrasion resistant, shock resistant, corrosion resistant, heat resistant with higher melting point, low specific gravity, electrical insulation property and dimensional stability.
It requires no lubrication and can be machined and finished in ways similar to metals. This versatile plastic is available in general purpose injection moulding grades, glass fibre reinforced grade, plasticized grade and extrusion grades to suit diverse applications.
