Since many years, Pulcra has a strong expertise in producing top-quality leather chemicals based with an exceptionally high portion of renewable feedstock. Signature products of Pulcra like Peramit ML-N, Grassan PA, Sirial TIS MF or Drasil 608 contain more than 90% of renewable carbon in their formulation and have been used by generations of tanners. Now, Pulcra has launched the game changing initiative Pulcra Naturalis® which is focusing on the promotion of a product portfolio with a high content of bio-based carbon. All products grouped in this new portfolio contain at least 80% of renewable carbon¹.
