Showa Denko has been manufacturing Polychloroprene in both solid and liquid dispersions for over 50 years with consistency, high quality performance and customer satisfaction. Showa Denko had a joint venture with DuPont from 1963 up until 2002 and still currently uses the same manufacturing methods and formulations which were used when DuPont was our partner.

Product Name: Showa Denko Chloroprene
Chemical Name: Polychloroprene 
HS Code Number: Dry 4002.49.00, Latex 4002.41.00

Footprints:
1960 Established Showa Neoprene (JV: SDK 50%,Dupont 50%)
1963 Started Neoprene local production at Kawasaki.
2002 DuPont/Showa Denko joint venture terminated. Showa Denko took over 100% of the Chloroprene production plant in Japan.
2010 United States of America - Anti-Dumping Duty on Japanese chloroprene was lifted.
2012 Local stock available at our US warehouse.

Dry Grades:
Showa Denko Chloroprene has four different types: A, W, T and G.

Liquid Despersion – Latex:
Showa Denko Latex is available in both anionic and non-ionic forms.
Some of the liquid dispersions we offer are 671A, 750, 115, 842A, 654, 572, SD77S, AE101, 400.
