Cotton swab manufacturers can produce a variety of cotton swabs according to the specific requirements of users. The main difference between different types of cotton swabs lies in the length and material of the handle.
The size, shape and material of the cotton swab head, the retention, absorption and adsorption capacity of the solvent. Foam clinker, polyester material and cotton are all raw materials used to produce cotton swabs. The swab head can be processed by heating bonding, folding, or melting and welding. Some new cotton swab heads are spiral-shaped, which can wipe off more debris.
Cotton swabs made of polyester materials have low non-volatile residue (NVR), less particle shedding, and chemical resistance. Through the analysis of total organic carbon (TOC), it is found that cotton swabs woven from purified polyester materials can release fewer particles, have good restorability, and have a low background level of total organic carbon.
The materials used for handle production include polypropylene, nylon, glass nylon, glass polypropylene, wood or styrene. The handle length of the cotton swab (7-25cm) and the shape and size of the cotton swab (from 4mm to over 16mm) should be determined according to specific requirements. The handle can also be slotted to facilitate breaking.

The absorption capacity of cotton swabs varies from product to product, and there are various packaging forms, such as anti-static discharge packaging and packaging that meets the requirements of clean rooms. Pharmaceutical factories and those environments that use "current" GMP management require the use of sterile cotton swabs. Some cotton swabs are produced using non-adhesive materials.
