100% biodegradable material to offer same technical performance like materials traditionally used

BildThanks to the collaboration between API, a leader in elastomers and biodegradable compounds, and DLM, a leader in hydraulics and hydropneumatics, the first protective cap for quick connect couplings in 100% biodegradable soft material has been created.

The protective caps for quick connect couplings offer protection from earth, rain and possible damage to the delicate hydraulic connections of the hydraulic systems present in tractors and earth moving machinery.

The materials traditionally used for this application are PVC and SEBS based compounds. The main characteristics required for this application are good resistance to UV and also temperature and weather resistance for lengthy and undefined periods of time.

While in use, protective caps for quick connect couplings often fall to the ground.

This gave rise to DLM’s desire to create a line of products with a low environmental impact through the design of 100% biodegradable protective caps for quick connect couplings that can be completely absorbed into the ground without, in any way, harming the environment.

The challenge for API was to create the formulation of a 100% biodegradable material that could offer the same technical performance of the materials traditionally used for this application while also being suitable for transformation using the machines and moulds designed for PVC and SEBS compounds.

By carrying out some modifications to the rheology of the base material and by acting on the relative composition of the constituents, API has developed a special grade of APINAT Bio perfectly suitable to be worked using the equipment available and with the required technical performance for this application.

This latest application development of APINAT Bio further confirms and reinforces API’s commitment to supporting more innovative companies who are sensitive to the growing environmental problems related to creating objects with a low environmental impact.
