Polymer & Plastics Calculators and Engineering Tools
Each tool answers one production question and returns a number or a diagnosis you can act on — dosage, density, shear rate, cost, defect cause and test method.
- Masterbatch Let-Down Ratio (LDR) CalculatorWork out the let-down ratio and kg-per-batch dosage for white, colour, filler and additive masterbatch, with the polymer matrix back-filled automatically.Use it when: A customer specifies a TiO₂, pigment or filler level in the part, not in the masterbatch.Open the tool
- Composite Density & Filler Loading CalculatorConvert between weight and volume in a filled compound: composite density, volumetric substitution and the real yield effect of calcium carbonate or talc loading.Use it when: You are raising calcium carbonate or talc loading and need the new part weight.Open the tool
- Apparent Die Shear Rate & Melt-Fracture PredictorCalculate apparent wall shear rate for slit and circular dies and see when the line enters the sharkskin and melt-fracture window.Use it when: The surface goes matt or shark-skinned when you push line speed.Open the tool
- Compound Cost per Tonne CalculatorBlend resin and filler prices into a single cost per kg and cost per tonne, and see the saving a given filler loading actually delivers.Use it when: You are justifying a filler loading change to a customer or to finance.Open the tool
- Extrusion Troubleshooting & Process Diagnostics MatrixFind the root cause of gels, black specks, sharkskin, die build-up, thickness variation and other extrusion defects, with the checks and remedies for each.Use it when: The line is running but the product is being rejected.Open the tool
- Polymer QC Standards & Test Method MatrixSearch the ASTM and ISO methods used to qualify masterbatch, fillers and compounds — ash content, MFI, dispersion, moisture, tensile and colour — with practical limits.Use it when: You are writing or auditing an incoming-material specification.Open the tool
