Светостабилизаторы на основе затрудненных аминов (HALS) защищают полимеры от разложения под воздействием УФ-излучения, нейтрализуя их. HALS регенерируются во время нейтрализации и продолжают обеспечивать защиту в течение всего срока службы конечного продукта. Они также действуют как первичные антиоксиданты с низким цветообразованием.
