  HOME Company Overview Enquiry Form
"ULACOL" is natural rubber latex with an extremely low ammonia content developed by our company, having a very slight ammonia odor.
Conventional commercial products of natural rubber latexes include "HA latex" and "LA latex" with ammonia concentrations of 0.7% and 0.25%, respectively. "ULACOL" is natural rubber latex with an excellent stability and a very slight ammonia odor, which is manufactured to achieve a reduced ammonia concentration of about 0.1% and with the use of low-toxicity preservative.
In the recent emphasis on VOC and environmental concerns, focus is returning to natural rubber latexes made from biomass materials which are carbon neutral. However, the pungent ammonia odor was a problem in many cases. This problem can be overcome by the use of "ULACOL", with prospective applications in fields that have been unexplored due to the pungent odor, as well as in the conventional market.
In addition, we offer modified products of "ULACOL" including prevulcanized latex and MG latex (MMA graft copolymer), to help expanded applications in new fields.

Note: Please be aware that "ULACOL" is manufactured in small lots due to the nature of developed product.
