Polypropylene
This material is the lightest of all thermoplastics (density 0.90 g / cm3.). If on the one hand it is non-toxic, on the other hand it is very weather resistant (dark colors) with durations close to 20 years in adverse conditions of the average type. At room temperature, it resists virtually any type of chemical attack and at temperatures around 70 ° C does not become vulnerable to chemical agents. Easy to work with all types of tools, both wood and metal used, are highly recycled plastics with low impact on the environment. In order to achieve more hardness or abrasion resistance, this material must be reinforced with Fiberglass (PP-GF) loading.
