OXO- Biodegradable (OBD) Additive

OBD is a degradability-promoting plastic additive that is comprised of a proprietary blend of prodegradants, stabilisers, and fillers in a polyethylene (PE) carrier.

Typical Applications

OBD can be incorporated into PE to make translucent and opaque flexible products such as PE garbage bags, carrier bags, mailer envelopes, aprons, gloves, and ponchos.

Prescribed Addition Rate

3-4% by Weight

Product Specification

Oxo-Biodegradable

Colour 

The color of OBD additive may vary from light to dark purple due to the nature of the raw materials, processing and storage conditions. Consequently, finished products incorporating OBD might vary in tint and may be more noticeable if the product is stacked together or in a roll.

Food Contact Status

OBD additive comply with the Federal, Food, Drug and Cosmetics Act (FDA) C.F.R. Chapter 21, and the European Union Regulation EU No 10/2011 on food contact plastic materials and articles applicable to all EU Member States.

PS Calcium Carbonate Compound

Modify physical property of plastics, act as plastical modifier.

Replace petroleum resource, reduce production cost. Environmentally friendly.

Improve printability, smoothness, hardness, stiffness, anti-block...

PS chalk masterbatch: used for PS sheet extrusion, PS injection mould..., one of masterbatches modifying polystyrene resin.

  • Processed by the four paddle rotor internal batch mixer or twin screw extruder.
  • Calcium carbonate master batch for transparent HDPE film available now. Adding by 5-10%, transparency becomes better in some cases; adding by 10-30%, transparency is still good enough. It's also good for LDPE film, HDPE pipe and PP sheet, which are transparent, but not very transparent.
  • Rub the film, CaCO3 (powder) and/or talc (powder) are not found.
  • Pellet is round and flat in shape, smooth feeling, well plastified, good dispersibility.
  • Ideal additive, harmless, no toxin.
  • Save cost, reduce expenditure, strengthen competition.
  • Professional process: CaCO3 (powder) and/or talc (powder) are coated and activated by unique coupling agent, dispersant and plasticizer before CaCO3 (pellet) and/or talc (pellet) are produced.
  • Special formula: CaCO3 compound and/or talc compound do not apparently side effect physical property of PE film, sometime the tensile strength of PE film becomes better after adding CaCO3 compound and/or talc compound.
  • Plastic chalk masterbatch named as chalk compound,chalk additive,chalk-filled extender,granulated chalk-filler composite,plastic CaCO3 agent,CaCO3 extender,CaCO3 granule.
