Bio-based TPE

Bio-based TPE

Bio-based thermoplastic elastomers (TPE) are eco-friendly materials made from renewable biomass resources that combine the elasticity of traditional rubber with the processability of plastics. CD BioSustainable is committed to revolutionizing the application landscape of traditional thermoplastic elastomers (TPE) through bio-based materials. We offer a comprehensive range of bio-based TPE products made from renewable biomass resources (such as corn stover and castor oil). While maintaining the excellent elasticity, wear resistance, and processability of traditional TPEs, these products significantly reduce the carbon footprint and dependence on petroleum resources.

The Advantages of Bio-TPEs

Mechanical Robustness

Early Bio-TPEs faced criticism for inferior strength compared to petroleum-based versions. However, recent formulations have shattered these barriers:

• High-performance polyester TPEs: Incorporating 2,5-FDCA yields materials with comparable heat resistance (up to 150°C) and oil resistance to commercial polybutylene terephthalate (PBT), while reducing emissions by 40%.
• Nanocomposite Bio-TPEs: CNC-reinforced variants achieve 1.5–7 times higher tensile strength than silicone, making them ideal for load-bearing applications like automotive seals and biomedical implants.

Thermal and Chemical Stability

Bio-TPEs exhibit remarkable stability under extreme conditions:

• Thermal endurance: Polyester-based Bio-TPEs maintain integrity at temperatures exceeding 120°C, rivaling petroleum-based TPCs (thermoplastic copolyesters).
• Chemical resistance: Materials synthesized from bio-propylene glycol (Bio-PDO) resist hydrolysis and oxidation, ensuring longevity in automotive fluids and industrial solvents.

Environmental Impact Assessment

Life cycle analysis (LCA) confirms the ecological advantages of Bio-TPEs:

• Carbon footprint: Producing 1 kg of Bio-TPE emits 3.2 kg CO2eq, compared to 7.8 kg CO2eq for petroleum-based TPEs.
• Biodegradability: Certain Bio-TPEs degrade within 6–12 months in industrial composting facilities, unlike conventional plastics that persist for centuries.

Our Products

Bio-based thermoplastic elastomers (TPE) are a class of elastomers made from bio-based materials, which usually have the characteristics of elasticity, durability and renewability. The TPE materials we can provide have a bio-renewable content base ratio ranging from 22% to 75%, with different hardness levels, good performance retention, UV resistance and flame retardancy, which are comparable to traditional TPE.

Features

• Biomaterial derived from plants
• Contains 22% to 75% biorenewable content
• Easily pigmented natural colors
• Good property retention
• Resists UV degradation
• Meets stringent flame retardant requirements

Applications of Bio-based TPE

• Automotive Industry: Used in sealing strips, hoses, and interior components. Advantages include lightweight construction, oil resistance, and reduced VOC emissions, which help extend the range of electric vehicles.
• Healthcare: Used in catheters, gloves, and wearable patches. Advantages include biocompatibility, biodegradability, and non-toxicity.
• Consumer Goods: Used in shoe soles, phone cases, and toothbrush handles. Key advantages include a soft texture and eco-friendly, low-carbon properties.
• Industrial and Electronics: Used in seals and cable jackets. Key advantages include heat resistance (some with melting points >240°C) and durability.
• Packaging and 3D Printing: Used in sustainable packaging and printing filaments. Key advantages include recyclability and a low carbon footprint.
