Polyester polyols for urethanes have been available for many years and have served the industry by offering outstanding tensile strength, tear strength, solvent resistance, UV resistance and flexibility.

Hanmathane PPDI based TPU are ability to deliver high performance under extreme conditions，where heat resistance, chemical resistance and superior dynamic mechanic properties are required, is enabled by PPDI (p-phenylene diisocyanate) that imparts exceptional properties to polyurethane elastomers.

Features: PPDI is acromatic isocyanate to make PU products with high temperature and compression resistant properties. Applications: Used in TPU and CPU products like wheel & caster, seal & gasket, belt & tube

Mar 1, 1992 · One striking feature of PPDI is how little hard segment is required to achieve a given hardness or modulus. In a PTMEG 2000 system, only 17 wt % of a PPDI/BDO hard segment was required to produce a modulus comparable to that of a 45 wt % MDI/BDO hard segment system.

Current guidelines for primary prevention defibrillator insertion (PPDI) encompass a heterogenous patient group which may include groups experiencing limited benefit or harm from PPDI. This study reviews PPDI with HF, its benefits and complications.

The present study aimed to compare the 2 available measures of pain-related disability in the German language, the Functional Disability Inventory (FDI) and Pediatric Pain Disability Index (PPDI), in terms of psychometric properties and convergent validity.
