Our Company
Qingdao Best New Material Co.,Ltd. was established in 2014.registered capital is $ 8 million ,located in Qigndao National Hi-tech industrail Development Zone ,is one of the key high-tech enterprises supported by Qingdao government .we are engaged in the research and development of innovation functional polymer including Color Masterbatch ,functional master batch and Modified Material .The annual production capacity is above 10000tons .we introduced advanced management concept and purchased advanced double skewed equipment as well as some other fine inspeciton instrument to provide comprehensive development plan ,the professional service and stable quality for customers . 

The PP(Polypropylene ) Oil Melt-blown Material  Electret Masterbatches for the surgical mask N95 mask  medical mask 



In view of the Kn95 and the medical  mask and the surgical mask  material uses melt-blown cloth special requirements, Qingdao Best New Material successfully developed a new material and good spinnability, high charge storage rate, strong persistence, wet and heat resistance of composite functional in muli, USES the advanced mixing extrusion process, the high flow melt-blown material production technology combined with in a function, and use the shear rheological ultra dispersion technology, developed the electret in resin can reach nanoscale (100 nm) or less dispersed electret masterbatch-ZJ-01A.
Qingdao Best New Material Electret masterbatch ZJ-01A is no need to add new equipment, and there is no need to significantly adjust the existing melt-blown non-woven production process.
The spinnability is good, the spinneret is not blocked, and the continuous production cycle is long, which does not affect the normal cleaning cycle and service life of the spinneret. Under the condition of the same fiber fineness and the same weight, it can reduce the resistance of the non-woven fabric products, and at the same time improves the filtration efficiency and self-sterilization performance of the non-woven fabric products.
It can be widely used in polypropylene(pp) melt-blown spinning process and high-performance non-woven fabrics, especially suitable for meltblown cloth for disposable medical and civil masks.
We all know that there are many electret masterbatch suppliers in China,as well as different quality level,our advantage is we keep the products quality in stable during the past 3 years,which get good feedback from our partners.
Whats' more,with the reply of our partner,with our ZJ-01A electrets masterbatch,their meltblown can easily passed the FFP2(Sodium chloride test 95l/min) and FFP3(Paraffin oil test 95l/min),that means such kinds of material will get the certification of EU and USA market.

Melt spray electret material -- ZJ-01 and melt spray PP raw material are mixed evenly in accordance with the ratio of 1.0 to 4.0wt% and then directly processed by melt spray spinning.The proportion of 4.0wt% is added online. Due to the different fineness and accumulation density of the melt spraying cloth fiber produced by each melt spraying line and the different discharge efficiency of electret equipment, the customer can increase or decrease the dosage of ZJ-01 according to the specific situation to achieve the best application effect
