Is ExxonMobil non-woven polypropylene 3155E5 so difficult to surpass?

  • Release on:2019-10-28
The newly added capacity of polypropyleneequipment has increased sharply. It is estimated that the newly added capacitywill be 10 million tons from 2019 to 2020. The new petrochemical enterpriseswill list polypropylene for non-woven fabrics as one of the key developmentgrades.

Lightweight, soft and functional non-wovenfabrics have become a hot spot for development. Polypropylene resin is requiredto have better fluidity. It meets the requirements for the production ofultra-fine denier non-woven fabrics from the 3rd generation of German Leifenand 4th generation high-speed production lines. 1.0 to 1.5D, even reaching 0.5to 0.9D.

1.Additive development hot spot:

Low odor, high efficiency, high flowperoxide degrading agent

Imported and domestic non-woven polypropylene special materials such as EXXON3155E5, Secco 2040, LuoyangPetrochemical Y35X, etc. are all produced by peroxide degradation method.

The peroxide breaks the molecular chain of the polypropylene(China PP Nonwovens On Sales), improves the melting index, makes the molecular weight distribution more uniform, and improves the spinnability.

As a non-woven material standard label,EXXON3155E3 has the advantages of low odor and good spinnability, and petrochemical companies have followed suit. In addition to catalysts, polymerization processes, propylene raw materials and other influencing factors, peroxidede gradation agents with high efficiency of degradation, low peroxide residueand low odor are hot spots.

Commonly used liquid peroxides, such asperoxide 101, etc., with the increasing safety of transportation and storagesafety requirements, liquid peroxides are flammable and explosive, and solidperoxides have become petrochemical enterprises. Preferred product.

Auxiliary manufacturers can pay attentionto the development of solid peroxide masterbatch, pay attention to safety, lowodor, low residue, low added amount, meet the needs of petrochemical enterprises

2.Additive Development Hotspot:

High-efficiency, color-resistant antioxidant additive package development

Non-woven fabrics for high-end medical and medicinal materials have high requirements for whiteness and yellow ingresistance. When peroxide is added during production, antioxidants are consumed,and yellowing of polypropylene resin is easily caused, resulting in non-woven production. The color of the cloth is yellow or red. The non-woven fabric isstored in a hot and humid environment, and it is prone to discoloration,resulting in defective products.

Auxiliary manufacturers can focus ondeveloping high-efficiency antioxidants that are resistant to discoloration,which can stabilize the melting index of polypropylene, ensure the oxidationinduction period is qualified, ensure the stability of production, and make polypropylene have better processing fluidity during spinning. Non-woven fabrics(Polypropylene Non Woven Fabric Vendor) have better appearance, storage stability and quality.

3.Additives Development Hotspot: High FlowProcessing Aids

Few petrochemical companies have reportedthe addition of lubricants and processing aids to improve fluidity and spinnability in the production of non-woven polypropylene.

Foreign petrochemical companies are alsodifficult to obtain information on processing aids due to technical confidentiality.

Auxiliary manufacturers can learn from theprocessing aids such as PPA organic fluorine additives added to polypropylenefor film and pipe to improve the extrusion efficiency of blown film and pipe,and study the effect of adding processing aids in polypropylene to improve thespinnability.

The real expectation is the use ofprocessing aids (non-fluorine additives) instead of peroxides to achievehigh-speed fine-denier spinning.

4.Additive development hotspot:

Safe, non-irritating, antibacterial aiddevelopment

With the advancement of society, non-woven sanitary products(PP Non Woven Materials Manufacturer) for medical, women, children and the elderly have put forwardhigher requirements for antibacterial, antibacterial and deodorant. At present,the petrochemical plant has tried to develop antibacterial polypropylene non-woven professional materials. Yangzi Petrochemical and Zhenhai Refining have made active attempts to reach the scale of batch production of 100 tons of antibacterial polypropylene resin.

N40Q, an antibacterial polypropylene special material developed by Zhenhai Refining & Chemical Co., was promotedand applied in Shanghai Fengwei Garment Accessories Co., Ltd. and JinjiangBaisida. The feedback was good.

Auxiliary manufacturers can focus on the development of antibacterial additives with high safety, discoloration resistance, small particle size and dispersion, which can meet the demand forhigh-speed production of fine-denier antibacterial non-woven fabrics.
