LY-1801HT (High-Temperature-Resistant Series)

● The LY-1801HT product is a high-end formulation specifically developed based on the LY-1401HT, with an emphasis on superior resistance to high processing temperatures. Its as-produced particle size conforms to the factory standard of 1.7–2.0 μm (internal control standard: 1.7–1.9 μm), featuring tight particle-size control and exceptional stability in performance metrics. The product exhibits large, uniformly sized primary crystallites, high crystallinity, low impurity levels, and high purity, virtually eliminating defects such as low crystallinity or fine fragmentation that could compromise its ability to withstand elevated processing temperatures. ● Due to its coarser final particle size, the LY-1801HT allows for greater control over primary crystallite size and crystallinity, resulting in excellent processability when used in cable applications, enabling higher filler loadings and even higher processing temperature limits.

Product Features:

● The LY-1801HT product is a high-end formulation specifically developed based on the LY-1401HT product to meet the requirement of higher processing temperatures. Its as-manufactured particle size is standardized at 1.7–2.0 μm (with an internal control specification of 1.7–1.9 μm), featuring tight particle-size control, excellent stability of performance parameters, large and uniform primary crystal grains, high crystallinity, low impurity content, and high purity. Importantly, it virtually eliminates defect crystals—such as low crystallinity or fine fragmentation—that can adversely affect processing temperature.

● LY-1801HT, with its coarser final particle size, allows for greater control over the original crystal grain size and degree of crystallinity. When used in cable applications, it exhibits excellent processability, enables high filler loading, and withstands higher processing temperatures.
