Occasionally Used Materials in Rotomoulding |
Occasionally Used Materials:
The rotomoulding process is favored by various companies for its cost effectiveness and ability to mold the most intricate & elaborate shapes that are impossible to be made using other similar processes. The process can mould a number of materials in different shapes, among which few of the occasionally used are Aluminum, ABS, Acetal, Epoxy etc. All these infrequently used material are discussed below:
| Aluminum |
Aluminum is used in various industries for various purposes specially in moulding and casting. The main moulding process in which aluminum is used is the Aluminum rotational moulding process which requires moulds, polymers (or resin), and the appropriate machinery. Aluminum plays a very essential role in moulding and casting in the industry.

| ABS(Acrylonitrile butadiene styrene) |
The word ABS is formulated from Acrylonitrile, butadiene, and styrene and carbon. Its primary attribute is its conjunctive strength and rigidity of styrene and Acrylonitrile polymers along with the toughness of polybutadiene rubber.

|
| Acetal |
Acetal is a popular and highly used polymer. Acetal is used in rotational moulding process due to its strong and flexible feature. It is a excellent resistance of oils, acetate and alcohols and a bad resistance of acids, it is highly recommended that acetal should not be used with any sought acids.

|
| Epoxy |
It is also an occasionally used materials in the rotomoulding process. Epoxy, also called polepoxide, is a a highly cross-linked thermosetting polymer which is produced when the epoxide resin reacts with a polyamine hardener. These polymers possess excellent electrical properties, low shrinkage, good adhesion to many metals and resistance to moisture, thermal and mechanical shock.

| Flurocarbons |
Fluorocarbons are organofluorine compounds that are designed to resist corrosion from insect repellent, gas or battery acid and sun damage. It does not soak up water or elongate like nylon and is almost undetectable under the water surface due to its rate of light refraction, which is equivalent to the rate of refraction of light in water.

| Ionomer |
Ionomers are polymer with ethylene as the major component but contains both covalent and ionic bonds in their chemical structure. The covalent bond generally exist within the elements of the chain while the ionic bonds are formed between the chains.

|
| Polybutylene |
Polybutylene is a strong and stiff semi-crystalline thermoplastic. It is abbreviated as PBT and has the appearance of white or off-white. This impact strength polyolefin or saturated polymer has the tendency of crystallizing very easily; this being the main reason for its use in the industrial scale molding.

|
| Polyester |
In the 20th century, polyester is developed from air, coal, petroleum and water. This synthetic fiber has an ester function group. This group is the result of the chemical reaction of carboxylic acid and alcohol. Most of the known polyesters are thermoplastics, however there exist few that are thermostats.
