The Core Role of Microcrystalline Wax in Crayons
Enhancing Product Performance: Microcrystalline wax possesses excellent flexibility and high elongation, effectively increasing the plasticity and flexibility of crayons, making them less prone to breakage. Simultaneously, it prevents oil migration, avoiding grease seepage that could contaminate packaging or surfaces, and facilitates demoulding during production.
Improving Production Processes: Microcrystalline wax exhibits excellent compatibility with paraffin wax, various mineral waxes, vegetable waxes, and pigments, ensuring thorough blending and uniform crayon texture. Its broad melting point range (typically 60–90°C) allows adjustment of overall crayon hardness, melting temperature, and solidification rate by selecting waxes with different melting points.
Expanding application domains: Microcrystalline wax is a key component in manufacturing water-soluble crayons. When combined with non-ionic emulsifiers, it enables crayons to self-emulsify in water, facilitating easy cleaning. It is also employed in producing multi-coloured and eco-friendly crayons to enhance tactile feel and antimicrobial properties.
