Our PHMG and PHMB are widely used in industries such as healthcare, personal care, water treatment, textiles, coatings, and plastics.
PHMG product series: Select the appropriate grade
We supply PHMG with four main product lines. Our R&D team can match the active ingredient content, physical form, and salt type according to application requirements to meet a variety of needs.
Production capacity: geared towards large-scale production and stable supply
Production base
Hebei Jinhong Chemical's core production base is located in Tangshan Caofeidian Nanpu Chemical Industrial Park, covering an area of 27,000 square meters and a building area of 5,800 square meters. It has an annual production capacity of 100,000 tons and is adjacent to Tianjin Port, allowing for direct sea transport.
Our production base in Tianjin (Tianjin Kewei Jinhong Environmental Protection Technology Co., Ltd.), established in 1988, provides synergies between research and development and production for our formulation work.
three production bases operating in tandem, a shutdown of one production line will not affect your orders.

Quality control
Our end-to-end inspection covers raw materials, the production process, and finished products. The company has an in-house testing laboratory, a complete batch traceability system, and long-term third-party testing partnerships, meaning defects are detected as soon as raw materials enter the warehouse, not at your receiving terminal.
For shipping, we are located near Tianjin Port and cooperate with more than 50 logistics providers. For large clients and project orders , we can deliver on time.

FAQ
Q: Does this product cause bacterial resistance?
A: No. It acts via a non-specific electrostatic mechanism, making bacterial resistance highly unlikely. PHMG is specifically designed to avoid this issue.
Q: What is the recommended usage concentration?
A: The recommended concentration is 0.05%–0.5% of active ingredient, depending on the application.
Q: Is it corrosive to equipment?
A: No. It shows no corrosion to metals such as stainless steel, copper, carbon steel, as well as wood and plastics.
Q: Can samples be provided free of charge?
A: Yes, samples are available free of charge. However, the customer is responsible for the shipping cost. This amount will be deducted from or refunded against a bulk order.
