The Golden Compound GmbH was founded in 2014 and has been a wholly-owned subsidiary of SPC Sunflower Plastic Compound GmbH since the beginning of 2016. Since its foundation, we have been intensively engaged in the development of materials with sunflower seed hulls. In October 2014 we started the annual production of 3,000 tons S²PC (Sustainable Sunflower Plastic Compound) and the marketing of our compounds in a newly built plant in Ladbergen, North Rhine-Westphalia. Currently our portfolio includes different materials: GOLDEN COMPOUND pro (durable) and GOLDEN COMPOUND green (home compostable) and are continuously expanding our production capacities.
Around 12 million tons of plastic material are processed every year only in Germany -more than in any other country in Europe. However, fossil resources are limited. For this reason we intend to avoid the use of mineral oil-based plastics wherever possible.
We use up to 70 % sunflower seed hulls as filling and reinforcing material for our compounds. These are obtained as a by-product of the food industry. Thus we are relying on an existing, quality-controlled supply chain and are not in competition with food production with the sunflower seed hulls.
Each year around 30 million tons of sunflower seeds are produced worldwide. The hull share is about 20 %, that means 6 million tons. The most important producing countries are Europe, Russia, Argentina and China. We obtain our raw materials mainly from EU countries.
Resource conservation is becoming increasingly important in the plastics industry. You will also be contributing to more environmental protection: with GOLDEN COMPOUND. Our innovative materials with up to 70 % natural fibers of the sunflower seed hull help to improve your CO2 balance, sustainably reduce your costs and are even home compostable, depending on the application.
GOLDEN COMPOUND has developed a series of innovative solutions by filling plastics with sunflower fibers. Our materials can be used in various compositions to replace PP, PP with mineral fillers, glass fiber reinforced PP, PS and aluminium with regard to the material properties and application requirements.
General usage
Our standard material GOLDEN COMPOUND pro with 35 % by weight of fibers has comparable properties to PP with 20 % by weight of mineral fibers.
Reductions of sink marks and density
Natural foaming of the fibers helps to avoid sink marks in thicker parts and reduces the density after processing to the finished parts to 1 g / cm³ despite a fiber content of 35 %.
Reduction of cycle times
The cycle time for applications where PP is replaced by GOLDEN COMPOUND pro, can be reduced by up to 50 %, especially for large parts. This results in a significant reduction of overall system costs.
Easy processing
Compared to WPC materials, GOLDEN COMPOUND pro is very easy to process and shows an uniform fiber distribution. If processed correctly, no “tiger stripes” occur.
Processing shrinkage
The polymer matrix of our compositions generally consists of polypropylene and shows a similar shrinkage as filled polypropylene materials. However, special compositions have been developed which show a material shrinkage comparable to styrene.
Increased impact resistance and stiffness
For applications which require increased impact resistance, the impact modified variants GOLDEN COMPOUND pro 15IM16 or GOLDEN COMPOUND pro 3545 10V34 are suitable. And for applications requiring increased stiffness, the previously used glass fiber reinforced PP, was successfully replaced by our GOLDEN COMPOUND pro 3545 with 35% by weight sunflower fibers and 20% glass fiber.
