Speciality chemical company BrüggemannChemical (Heilbronn / Germany; www.brueggemann.com) is offering compounders and producers the ability to adjust the relative viscosity of polyamides. According to the company, its newly developed modifier "Bruggolen" TP-M1417 allows upcycling of high-viscosity PA scrap to produce injection-moulding grade material, at a "significant" cost benefit compared to the use of virgin polymers.

Bruggolen TP-M1417 gives PA scrap "high stiffness, tensile strength and impact strength," and these upcycled materials are suitable for the same applications as virgin material of corresponding viscosity. The new modifier is supplied as dust-free granules that enable accurate quantities to be measured out. It can also be used to modify the relative viscosity of virgin PA material during the compounding stage, which the company says results in gains in flexibility and reductions in the amount of off-spec material.

BrüggemannChemical specialises in manufacturing high-performance additives for engineering thermoplastics, with a focus on polyamides, in addition to zinc derivatives and sulphur-based reducing agents. The company has approximately 200 employees as well as subsidiaries in Hong Kong / China and Philadelphia, Pennsylvania / USA.
