1 is a granulate developed for compounders to improve processing and properties of bioplastics. is a biodegradable granulate based on vinyl and lactic acid homo- and/or copolymers. Version 01 / Date For processing information: Our technical services department is available to discuss your requirements and advise on the best grade selection for products & (color) masterbatches. PORTFOLIO The main standard portfolio of the Optinyl grades contains masterbatches with properties like traditional masterbatches but dedicated for the compounders plastic market. Various Optinyl products are available to be able for compounders to anticipate on various themes. Dedicated types or specialty grades can be made available as well. New grades our continuously developed, such as grades with higher flexibility, higher biobased content, different base polymers as well as lower costs varieties. Our technical services department is available to discuss your requirements. Compatibilising additive polymer masterbatches (Optinyl COP types) are especially designed for blending for the compounding industry to obtain: Blends with thermoplastic starch or polyesters (PBAT, PLA, PHA, PBS) Polyolefins (PP) - fibre composites Polyolefins starch hybrid composites APPLICATION is an easy to process masterbatch developed to improve the processing and properties of various polymers and polymer-fibre blends. Optinyl COP2342 is a masterbatch suitable for translucent and glossy applications and is specially developed for compounders to improve the impact or strain properties of injection molded and extrusion based biopolyester products (in particular PLA). can be processed on conventional compounding lines. Optinyl COP2342 is a competitive alternative for currently used biodegradable masterbatches for a wide range of applications. has a natural feel and look. is biodegradable and has a biobased or plant derived material content of > 40%. is an easy to melt masterbatch that will provide a good homogeneous dispersion in your compound and thus end product (e.g. Sheets, Thermoform, Trays, Lids, Molded products). Applications in which Optinyl COP2342 is used: Packaging & Consumer goods Agriculture & Groundworks products Technical products Automotive FIGURE 1: EFFECT OF OPTINYL COP2342 ON IMPACT AND STRESS-STRAIN FOR PLA Products are based on extrusion grade PLA. Materials were made via two-roll mill and compression molding. Product properties depends on amount of COP2342 used. Optimal amounts can be different for different polyesters/polyolefins & products (foils, sheets, molded products). FIGURE 2 - RHEOLOGY Influence on viscosity at 170 & 190ºC compared to biopolyesters (PLA PBAT) & FlourPlast thermoplastic starch. COP2342 has a low viscosity giving enhanced processing at high shear processing conditions & lower processing temperatures.

Material Safety Data Sheets are provided to help customers satisfy their own handling, safety and disposal needs, and those that may be required by locally applicable health and safety regulations, such as OSHA (U.S.A), MAK (Germany), or WHMIS (Canada). CHEMICAL CONTROL LAW COMPLIANCE Across the globe regulations exist for local environmental authorities to evaluate materials to assure the protection of human health and the environment from any unreasonable risks associated with chemical substances. Components used in Rodenburg Biopolymers resins as supplied from the factory gate comply with the European Union (EINECS)/REACH chemical inventory. DRYING is packaged during manufacturing to keep moisture low. However (off- or in-line) pre-drying will improve properties & is recommended before processing. A moisture content of less than 0,025% (250 ppm) is recommended to prevent hydrolysis and loss of properties. Typical drying conditions are 4-8 h at 45ºC or to a dew point of -35ºC, with an airflow rate greater than 0,5 l/s per kg of resin throughput.

The properties given must be regarded for guidance purposes only, since product is based on renewable raw materials with fluctuating properties by nature. Consequently the material has to be processed in accordance with our guidelines. PROCESSING can be processed on most standard extrusion / compounding machines, also with a low shear screw design and low temperature settings. is amorphous and can be processed at temperatures between ºC on most conventional extruders. Minimal processing T is ºC and maximally T used is 220ºC. Preferred processing T of the pure Optinyl is ºC for extrusion processing but higher temperatures need to be used if polymers combined with Optinyl require higher melting temperatures. Usually one can process Optinyl in combination with polymers at a melting temperature ca. 1-20ºC above the crystal melting T of the polymers in question. For instance for Ingeo 4043D one can process this in combination with 10-40% Optinyl at ºC. A reduction in amperage and die pressure is often seen after addition of COP2342 to a polymer even at a relative low processing T. A lower T reduces thermomechanical degradation of biopolyesters such as PLA and gives improved properties. Pre-drying is advised and-or degassing during compounding especially at temperatures above 190ºC. Typical use levels are 5-20% (possible use range 2-50%). Addition of Optinyl COP2342 to biopolyesters, like PLA, at an bioplastic production line results in a highly transparent to glossy product, depending on bioplastic type, with a very stable output. can be combined with various biobased and biodegradable products. Sensitivity towards water (hydrolysis of biopolyesters such as PLA) is lowered due to lower process temperature. FIGURE 5 Film blowing & casting an Optinyl based compound.

ADDITIONAL INFORMATION REMARKS & OTHER INFORMATION Presuming appropriate processing, the composition of product complies with FDA adhesive layers for food contact standard ( : The composition does currently not comply with , , ). As such has potential to be used in materials or articles which are not intended to come into direct contact with food. In order to comply, IPM2341 has to be used in accordance with good manufacturing practice (FDA 21CFR 174.5) for adhesives, i.e. separated from direct contact with foods by a functional barrier layer, or there is only trace exposure to the adhesive to aqueous or fatty foods at seams or edges of the laminate structure. In cases where a large ratio of surface area of the adhesive layer to volume of food is involved and where exposure levels are severe, extraction tests may be required to assure that the food contact layer will perform as a functional barrier layer. Compliance with the provisions of these regulations, especially the suitability of the articles for the given application, the effect on smell and taste of the food, and observance of any given limitations, must be ensured by the person who introduces the articles into circulation. The specific restrictions mentioned in EC Plastics Regulation No 10/2011 and amendments have to be ensured. Migration should be measured on finished articles placed into contact with the foodstuff or appropriate food simulants for a period and at a temperature which are chosen by reference to the contact conditions in actual use. CERTIFICATION is expected to be compliant with EN (industrial compostability / biodegradability, heavy-metal content, plant-toxicity) with tests pending. If is used in applications, other than those mentioned, the choice, processing and use of is the sole responsibility of the purchaser. All legal and other regulations must be complied with. TRANSPORT, STORAGE AND SHELFLIFE must be stored in a cool dry place, out of direct sunlight and protected against humidity. Product should be maintained in closed bag, preferably predried and processed in a closed humid free system within 1 hour after opening. Storage time should not exceed 1 year after date of production of the granulate. PACKAGING Packaging; 25 kg paper bags, big bags, super sacks or octabins.
