Factory & About
Manufactured in Shandong, built for export.
LINGLANG is the largest silicone sealant manufacturer in our area. From our plant in Linqu County, Weifang City, we formulate, fill and pack silicone, MS polymer and acrylic sealants for construction, glazing and general building.
Every product is manufactured to Chinese national quality standards, with raw materials, batches and finished cartridges checked before they leave the floor.
A dedicated foreign trade department handles export customers directly — from samples and private-label requests to documentation and container loading. Our focus is simple: consistent quality, and building each order around what the customer actually needs.
