Material Consultation

宁波万宠科技有限公司 (Ningbo Wanchong Technology Co., Ltd.) is a materials company under DEYU Plastics, specializing in the research, development, and manufacturing of plant fiber composite materials. In 2024, the company launched its new brand, wooyopet（万佑宠）, focusing on the compounding and industrial application of natural plant fibers with polymer materials.

At wooyopet, PET stands for Plant, Engineering, and Technology.

Plant represents our starting point: natural plant fibers.

Engineering represents the material engineering process that transforms plant fibers into stable, processable, and scalable composite materials.

Technology represents our continuous development of material formulations and processing technologies to expand the possibilities of plant fiber composites in modern plastic products.

Based on this philosophy, we combine natural fibers such as wheat straw, rice husk, coffee grounds, bamboo fiber, wood fiber, and coconut fiber with petroleum-based polymers including PP, ABS, PE, and PA. While maintaining practical processing performance and the functional requirements of finished products, these composites can reduce the proportion of conventional petrochemical plastics and introduce more recognizable natural fiber particles, textures, colors, and surface characteristics.

Supported by wooyopet's experience in polymer modification, wooyopet has established a complete material development system covering plant fiber selection and treatment, formulation development, laboratory trials, process optimization, and large-scale production. According to different product structures, manufacturing processes, and performance requirements, we can customize fiber type and loading level, base resin, material flow properties, impact performance, color, and surface texture. Functional development such as antibacterial and mold-resistant properties can also be evaluated according to specific project requirements.

wooyopet plant fiber composites are suitable for a wide range of applications, including household products, automotive interiors, consumer electronics, daily consumer goods, and pet products, and can be processed through common methods such as injection molding and extrusion. For pet-related applications, we have also developed dedicated material solutions with targeted optimization for bite resistance, stain resistance, and long-term use performance.

wooyopet aims to help brands, product design companies, and manufacturers introduce plant fiber materials into commercial products in a more flexible and practical way, balancing product performance, natural material aesthetics, cost control, and sustainability objectives. We support small-batch trials, custom color matching, fiber-content adjustment, and material performance development, and can assist with project-specific compliance requirements related to RoHS, REACH, FDA, and other applicable standards.
