TPE Transparent Material
Product Description
A thermoplastic elastomer with excellent optical clarity. Through special compounding and pure raw materials.
Key Characteristics
1. High Transparency & Light Transmittance: Visually clear with excellent light transmission.
2. Low Haze: Pure material with minimal light scattering and high image clarity.
3. Excellent Softness & Elasticity: Comfortable touch and good resilience.
4. Good Anti-Yellowing Properties: Optimized formulation to effectively retard yellowing under long-term use or light exposure.Main Applications
Transparent tubing, diving equipment (masks, snorkels), transparent medical device components, transparent seals, transparent toys, transparent protective cases and buttons for electronics, transparent household accessories, sports bottle spouts, industrial parts requiring sight windows.
Processing Methods
Injection Molding, Extrusion Molding, Blow Molding.
Environmental Certifications
ROHS, REACH, FDA (optional, grade-specific), LFGB (optional), Phthalate Free.
Color
Transparent, Ultra-clear. Transparent color masterbatch addition service available for colors like blue, red, yellow.
Odor
Very low or odorless.
Appearance
Crystalline clear uniform pellets.
Storage Conditions
Must be stored sealed in a cool (<30°C), dry, and dark place to prevent moisture absorption, contamination, and oxidative yellowing. Recommended shelf life: 12 months.

Parameters & Instructions
Drying Temp/Time
70-80°C / 3-4 hours (Mandatory! Moisture is the enemy of clarity, causing haze and bubbles)
Melt Temperature Range
150 - 180 °C (Strictly control at mid-to-low range to avoid thermal degradation and yellowing)
Mold Temperature
20 - 40 °C (Use high-gloss polished molds for best surface finish and clarity)
Injection Speed
Medium speed is suitable; avoid high-speed shear heating.
Screw Speed & Back Pressure
Medium-low screw speed, moderate back pressure for better plastification uniformity.
Critical Precautions
1. Cleanliness is Paramount: Any contamination (dust, other colored pellets, grease) will ruin transparency. Processing environment, equipment (hopper, screw, barrel), and molds must be extremely clean.
2. Drying is Critical: Thorough drying is essential, otherwise cloudiness, bubbles, and haze will appear.
3. Temperature Sensitivity: Highly sensitive to processing temperature. Excessive temperature or prolonged residence time causes thermal oxidation, leading to permanent yellowing and reduced clarity.Purge Suggestion
1. Dedicated Purge Material: Strongly recommend using transparent-grade LDPE or HDPE as a dedicated purge material.
2. Thorough Purge: Before switching from any non-transparent material to transparent material, multi-stage, thorough purging is mandatory until the purged material runs completely clear and colorless.
