Self-finishing refers to a material or product that does not require any additional finishing processes after production.

A type of polymer that becomes soft and moldable when heated and hardens when cooled, allowing it to be reshaped multiple times.

Material that, once set, cannot be remolded by heat. It undergoes a chemical change during the curing process, forming a rigid and durable structure.

A material at room temperature, that can be deformed under pressure and return to its original shape.

A material can break down using natural processes over a certain time period.

A product can degrade when exposed to UV light, breaking the bonds between particles.

A product can breakdown when exposed to oxygen breaking the bonds between molecules.

A product can break down when exposed to water, breaking the molecules between molecules.
