Testimonials
Our happy customers
“The food-grade PAE wet strength resin from LY Chem passed all our safety tests perfectly. It’s hard to find such low chloropropanol levels in the market. Highly recommended for tissue manufacturers.”
Michael Tan (Technical Director, Malaysia)
“Communication is smooth and transparent. From the initial inquiry to the final delivery, the LY Chem team kept us updated every step of the way. It makes importing chemicals stress-free.”
David Kim (CEO, South Korea)
“We use their rosin size for our specialty papers. The emulsion stability is excellent, even in our hard water system. It has significantly reduced our alum consumption.”
Elena Rossi (Purchasing Manager, Italy)
“We needed a urgent supply of defoamers during a peak season. LY Chem managed to expedite the production and shipping, saving our production line from shutting down. Exceptional dedication!”
