The difference between latex and non-latex powder puff
Latex powder puff
In fact, it refers to a powder puff made of natural latex, which many people are allergic to because it is rich in protein, especially in Europe. In order to reduce costs, many manufacturers will add talcum powder, and the powder will be slag.
Styrene butadiene latex
The emulsion is composed of butadiene and styrene emulsions. At present, styrene butadiene rubber is mainly used for powder expansion production, mainly referring to 341 Jinhu, South Korea. The unit price is about 17,000 yuan per ton.
Nitrile latex
It is an emulsion formed by polymerization of butadiene and acrylonitrile. At present, the NBR used in the production of powder puff mainly refers to the 531B of Japan's Rayon Company. The unit price is about 90,000 yuan/ton.
So what happened to the non-latex puff on the market?
At present, the domestic non-latex powder puff mainly refers to the powder puff made of hydrophilic polyurethane material. The feature is: the water will become bigger!
Latex powder puff
To distinguish by material:
1. NR Powder puff
Rough surface, easy slag, poor toughness, big smell!
2. Styrene butadiene rubber powder puff
The surface is fine, tasteless, tough, but the oil resistance and aging resistance are average.
3. Nitrile rubber powder puff
The surface is fine, odorless, very soft and hard. Oil resistance, aging resistance, long-term use is not easy to deformation.
4. Non-latex powder puff
It gets bigger in the water. The surface is more delicate, odorless, the color is brighter, and the feel is softer. But it can't withstand storage.
Latex powder puff
According to the production process:
Non-emulsion powder expansion can be divided into cover mold process, free foaming process, Q-PLUS process.
1. Capping technique
It bubbles up in a jar and then covers it. Powder puff will be harder.
2. Free foaming process
It also lathers in the jar, and without a lid, the puff will be softer.
3. Q-addition process
On the basis of free foaming, improve the formula to make the puff very soft! Skin feels good!
Of course, no matter what kind of material, quality is good or bad, the key lies in the manufacturer's process and the bottom line of doing things.
Comparison of extruding defects between emulsion powder and non-emulsion powder
1. SBR powder puff, which is not as soft, can be stored for a long time, but will give off a slight smell when unpacked.
2. Non-latex powder foaming: long-term extrusion easy deformation, not easy to restore the original state. Different colors of powder puff, put together for a long time, will be overcolored. It usually changes color after 8-12 months. After soaking in water, they are easily scratched and torn.
3. NBR Powder Puff: I think it is perfect, has good beauty effects, is durable, does not deform, and is especially suitable for powder cartridges.
