STDPOLY is a producer that specializes in the creation and manufacturing of superior quality PE masterbatches. Our expertise lies in our proprietary technology that relies on the rigorous methodologies of top-notch masterbatch manufacturers, allowing us to have full mastery over the behavior of different types of PE structures (LDPE/LLDPE/HDPE).
We do not promote a “one-size-fits-all” masterbatch.
Why?
Simply because:
A flow rate suitable for cast films is fundamentally distinct from the one required for large pipes. We always emphasize “custom carriers upon request,” guaranteeing that each masterbatch particle mixes seamlessly with your resin upon entering your equipment.
Carrier: PE(Polyethylene, LDPE/LLDPE/HDPE)
Let down ratio: 1-10%
MFI:5-1000g/10min
Mositure:＜0.3%
Quantity per bag/box: 25Kg/500-1000KG
Weight per box (kg) : 8-10kg
Wooden fumigated pallets: 15-20KG
20-foot container: weight＜ 20T; the exact quantity depends on the type of masterbatch.
40-foot container: weight＜28T; the exact quantity depends on the type of masterbatch.
PE masterbatch refers to the concentrate produced using polyethylene resin as the core ingredient, together with a large portion of pigments or additives (PPA, antistatic agent, slip agents). The compound serves as the major carrier that contributes to coloring and adding functionalities during the processing of PE plastic.
The broad applications of PE masterbatch are attributed to the fact that its structure can be easily adapted to a wide range of resins. Other types of resins also use the same compound for coloring and adding functionalities.
When applying our masterbatch to blown film and cast film processes, its filtration pressure will be very important to ensure there is no screen blockage or extruder die buildup. We can guarantee the absence of pinholes and gels when stretching the films at high speed.
For the purposes of milk, shampoo, and other bottles or even 20L industrial drums, the dispersion and MFI of our masterbatch are adjusted. We make sure that your bottles have a perfect cut at the bottle neck without decreasing its drop impact resistance.
Moreover, we meet the food-grade requirements (GB9685 or FDA).
We offer black, gray, green, orange, and red masterbatch for drinking water pipes. Moreover, you may require some specific features in such tubing like antibacterial action, flame retardancy, or even matte finish.
All your needs for food-grade conformity, UV stability, good dispersion and inter-batch consistency are met.
This is mainly due to inadequate surface treatment of titanium dioxide or improper dispersion in the masterbatch. Our highly concentrated white masterbatch has an extremely low filter pressure value (FPV). This will greatly increase the period between screen changes.
The bottom part of the blow molded bottle is thicker, so color accumulation happens there and becomes darker. The masterbatch’s color density and fluidity are controlled to make the color appear more evenly distributed from the thin to thick parts of the bottle.
Indeed. The natural property of carbon black is the high resistance of this compound to UV. It transforms harmful UV light to heat which doesn’t impact plastics adversely.
The appearance of such defects can be caused by moisture inside the masterbatch or incompatibility of the dispersant. First, dry your masterbatch and if the problem persists, contact our supplier for further help.
Without any doubts, you can. We provide special formulations for complex mixtures including recycling and thus enhance color effect while masking base color of recycled materials.
Yes, we produce antistatic PE masterbatch which can reduce surface resistance up to 10^9-10^11 ohms and is successfully utilized for packaging of electronic components.
