Spektrum’s frames are made of plant-based non-food derivates from corn. The details on our frames are made out non-food resin and castor bean derivates. 64% of the product is produced of plant based bio material and recyclable materials. Through our process they are modified into polymers and become pellets that are injected with color. The dye process ensures a superior durability and depth of colour for all our frames. This vastly improves colour performance, durability and scratch resistance. The process also spares workers and our environment from exposure to hazardous solvents and chemicals.
