Especially, its performance will be lowered under the effect of thermal oxidation, so when made into plastic coils, high-density polyethylene is often added with anti-oxidants and UV absorbers to improve the weakness. LDPE is non-toxic, tasteless and odorless, with a density of 0. It is produced through polymerization under the to MPa high-pressure conditions , by using oxygen or an organic peroxide as the catalyst, so it is also referred to as high-pressure polyethylene.
Low-density polyethylene is the lightest variant among all polyethylene resins. Its characteristics also include great electrical insulation and air permeability; low water absorption; and easy combustibility.
Its weaknesses are its deficiency in mechanical strength, moisture resistance, air permeability and resistance to solvents.
Its mechanical strength is lower than that of high-density polyethylene, and its anti-seepage coefficient, thermal resistance and resistance to aging caused by sun exposure are also rather poor. Under sunlight or high temperature conditions, it is prone to aging and discoloration, resulting in performance deterioration, so when made into plastic coils, low-density polyethylene is often added with anti-oxidants and UV absorbers to improve the weaknesses.
LLDPE is non-toxic, tasteless and odorless, with a density between 0. The molecular structure of conventional LLDPE is characterized by its linear backbone, with few or no long chain branches, but containing some short chain branches. MRW is a natural color available in a pellet and powder form, whereas M90 is the color compound version. This grade is suitable for rotational moulding of large water tanks and parts that require high stiffness.

SCG S11 is a color compound linear low density polyethylene specifically developed for rotational moulding applications.
With a balance of stiffness and toughness, a large processing window and a wide variety of color selection, S11 is suitable for kayaks, water tanks, playground equipment, and other general rotomoulded articles. This grade will exhibit excellent bonding to a polyethylene skin, which is critical when trying to increase the stiffness and impact resistance of a product. Foam can be used in existing designs to reduce overall weight and also increase flexural stiffness.
This product does not require specialist equipment, but a high level of process control is desirable in order to achieve consistent results. This product is available with a choice of three expansion densities, as indicated by the suffix, and is intended to be used as a second shot either utilising a drop box, or by manual addition.
