Is the filament of the artist paintbrush nylon or PBT?
Faced with a dazzling array of brushes in the painting material store, when choosing, do you know what the filaments of these oil brushes are?
The bristles of the oil brush are bristles, and there are also a small amount of wolf hair and chemical fiber materials. The bristles of oil painting brushes on the market are mostly made of chemical fiber. The well-known chemical fiber materials are nylon and PBT. So which chemical fiber material is used for the brush filament of the artist brush?
①Nylon：
Nylon is the generic name for a family of synthetic polymers called polyamides Nylon is essentially an organic thermoplastic (a synthetic polymeric resin) originally developed by DuPont.
Features
1. High temperature resistance
2. Durable
3. Easy to process
4. Not easy to fall off, with strong wear resistance (very suitable for cleaning and scrubbing applications)
5. Resistant to most common chemicals and has excellent bend recovery
It is the toughest and most durable synthetic filament available, and by its very nature it is found that this filament is suitable for household dusting and cleaning of medium-bristle brush parts.
In general, what do we use this raw material for?
Nylon: industrial brushes such as vacuum cleaner rollers, brush rollers, and brushes
②PBT
Polybutylene terephthalate (PBT) is a thermoplastic engineering polymer, a thermoplastic (semi)crystalline polymer, a polyester. PBT filament is a plastic filament that is close to nylon filament.
Features
1. High resilience
2. Easy to color
3. Soft texture
4. The brush wire is not easy to deform and has a long service life
5. Acid and alkali resistance, oil resistance, solvent resistance
6. Less water absorption, suitable for working in wet environment
PBT filament with excellent elasticity and flexibility is a high-quality filament. The costof PBT filament is lower than that of nylon, and the price of PBT brush will be cheaper.
In general, what do we use this raw material for?
PBT: paint brushes, artist paint brushes, polishing brushes, toothbrushes, bristle brushes.
