Empty silicone sealant cartridge

Longpower Hardware And Plastic Co., Ltd. produces empty silicone sealant cartridges that are supplied without any sealant content. The cartridges are manufactured in their Guangdong facility and are intended for refilling with standard silicone formulations used in construction, automotive and electronics sealing. The company states that it uses modern machinery to keep dimensional accuracy and alignment consistent across batches.

Typical silicone cartridges are built from aluminium extrusions with an inner PTFE liner to prevent sealant adhesion to the tube wall. Standard industry dimensions are a length of about 310 mm and an outer diameter of roughly 13 mm, with a tolerance of ±0.5 mm on each dimension. Capacity is generally 300 ml for empty cartridges, and the weight of a bare unit is around 150 g. These figures are common across the sector and help ensure compatibility with most cartridge guns and dispensers.

Buyers such as sealant manufacturers, adhesive distributors and OEMs often request empty cartridges to customise formulations or to meet specific regulatory requirements. The supplier indicates that it can meet bulk orders and will discuss packaging options, MOQ and Incoterms directly with the importer. Because the listing does not disclose price, minimum order quantity or lead time, interested parties should contact Longpower for a formal quotation and to confirm any certification requirements.
