Virgin and Recycled GPPS and HIPS: What Buyers Should Compare

Choosing a polystyrene material starts with a clear description of the finished product and the requirements it must meet. Our GPPS and HIPS ranges each include virgin and recycled categories, giving buyers separate material options to evaluate for their production needs.

Identify the Material and Supply Category

Keep GPPS and HIPS separate when preparing a material request, and state whether the enquiry concerns a virgin or recycled category. Include the current grade reference if one is already used in production. This creates a clear starting point for discussing a potential replacement or a new material.

Describe the Finished Part

Share the intended application, production process and the properties that matter to the finished part. Appearance, colour, dimensional requirements and mechanical requirements should be described individually. A photograph or drawing can help explain the part, while a written specification establishes the criteria for evaluation.

Compare Samples Under Consistent Conditions

Product photographs help communicate appearance preferences. For a purchasing decision, assess the proposed material through an agreed sample trial and record the production conditions and finished-part results. Colour and appearance alone do not establish the material grade or its suitability for the intended use.

Keep the Comparison Traceable

Record the sample identification, material category, trial date and evaluation criteria. When reviewing more than one sample, use the same acceptance criteria so that results can be compared meaningfully.

Prepare a Complete Enquiry

Send the material family, virgin or recycled preference, intended use, required quantity and relevant specifications. Include any testing or compliance documents required for the application. These details help focus the discussion on the material and documentation needed for your production process.
