Anti Uv Masterbatch UV 7 Bar

07/03/2018

UV 7 Bar is a masterbatch containing UV Absorbers in a LLDPE carrier resin. Masterbatch absorbs the UV radiation and gives excellent optical properties.

SPECIFICATIONS
% Anti-UV 17.8 18.0 MO211-700*
ADDITIONAL TYPICAL PROPERTIES
Appearance Slightly greenish pellets
Melt Index (190°C / 2,16 kg) 10 MO 1-700*
Specific gravity g/cm3 1.15 MO13-700*
Bulk density 0.63 0.66 MO28-700*
Ash content 25 27 MO5-700*

* POLYTECHS internal method

USAGE

UV 7 bar can be easily processed on both blown and cast film extrusion lines.

For thin films (about 20 mm) tests may be performed. UV7 Bar is used in shrink-wrap films to prevent both discoloration and loss of properties of contents.

RECOMMENDED ADDITION RATES

The table below represents recommended UV 7 Bar concentrations for different film thickness’ and the corresponding light stability (Kly) :

Quantity (%) Film 50 mm Film 100 mm Film 200 mm
1 30 kly 80 kly 130 kly
2 50 kly 150 kly 200 kly
4 100 kly 200 kly 300 kly
6 150 kly 320 kly 500 kly

Reminder:

  • 140 Kly = 1 year in Florida
  • 190 Kly = 1 year in Arizona
PACKAGING

Product is normally packed in 25 kg PE bags on 1375 kg shrink-wrapped pallets.

V 7 Bar是一种以LLDPE为载体的紫外线吸收剂母粒,起到吸收紫外线的作用,能赋予薄膜优异的光学性能。

用途

UV 7可非常容易地被用在吹膜和流延膜生产线中,对薄膜起到良好紫外线防护效果。

不推荐将其用于50μm以下太薄的薄膜中。

将UV 7用于外包装收缩膜中,既可起到防止薄膜变色的作用,又可防止被包装物品的变质。
